Trang 7Despite the fact that English Syntax is difficult to most English majors, it is still my
all-time favorite subject I had never been so sensitized to the complexity of English until attending the course I had simply thought that language is a clear and literal means for communication ideas; nevertheless, it was in the course that I discovered that even when we use language literally, misunderstanding may arise and meanings may shift (Clare, 2003; Jacobs, 2003) Therefore, it is obvious that such commonly
written sentences as (a) “Old men and women are served first” or (b) “My house is in the park near the forest” may confuse readers because they are open to more than one interpretation in meanings That is, readers may understand sentence (a) in two ways: (a1) Women and old men are served first and (a2) Old men and old women are served first Similarly, sentence (b) can be paraphrased as two ways: (b1) My house is in the park which is near the forest and (b2) My house is in the park and near the forest
Clearly, normally a word or syntactic structure has more than one meaning, in or in spite of its context (Newmark, 2001) This phenomenon is part of language and
defined as ambiguity in language As a result, towards a better communication in
which people understand each other without any barrier of language form and structure, ambiguities should be treated as a problem to be solved by language learners and users (Newmark, 2001; Clare, 2003; Jacobs, 2003)
The attraction of ambiguity has motivated me to constantly research into ways ambiguities in English are made, fields they are employed, and strategies to disambiguate ambiguities It is amazing that ambiguities have been employed in many fields, especially newspaper headlines, advertisement and poems to create dramatic effects on readers Both Hoenisch (2004) and Webber (2007) agree that lexical and
Trang 8structural ambiguities contribute to make newspaper headlines ambiguous and
humorous Such headlines as (a) Iraqi heads seek arms and (b) Stolen painting found
by tree are typical examples of ambiguity application in this field Headline (a) is lexically ambiguous because the word “head” can be a chief or a head of a body and the word “arms” can be both weapons and body parts Also, headline (b) may be understood as a stolen painting was found near a tree or a tree found a stolen painting In addition, puns which are resulted from ambiguities are frequently used in advertisement deliberately (Nguyen, 2002) The sentence “It’s not worth dying for a drink” is a good illustration of the use of ambiguity in the advertisement industry The phrase to die for a drink can be understood as to die because of a drink or to desire a drink” Therefore, we can paraphrase this sentence as it’s not worth dying because of a drink or it’s not worth desiring a drink Ambiguities also exist in poems like a poetic
vehicle although not everyone discovers them when reading (Tran, 2006) The
example “She lost the paradise with her first bite of the apple” which means “She lost the paradise as soon as she first bit the apple” or “She lost the paradise because she bit the apple” is a good evidence of ambiguities used in poems Obviously,
ambiguities occur in many fields of life even when we do not recognize them
Inspired by these interesting finds, I have conducted a small investigation into ambiguities I have made in a number of the compositions that I have written so far So surprisingly, I found that I seemed to write without a thought of what I wrote may have misled readers; a lot of ambiguous sentences were made in these compositions Many of them have later been improved according to the comments of my instructors; others still remained unchanged because these ambiguities were not recognized then, and if any, I did not know how to disambiguate them either According to Norvig (2006), although serious ambiguities may occur everywhere in sentences, not all readers and listeners but only linguists find them ambiguous by careful analysis It means that sometimes ambiguity is not discovered by the people who make it, but it may cause many problems when the others consider it to be ambiguous Ambiguity is then becoming a matter of concern for language learners and users; it is also a great challenge for teachers of English (Jacobs, 2003) From a perspective of a learner, I strongly believe that ambiguities are common and serious errors that may cause
Trang 9misunderstanding and misinterpretations; thus may disqualify the quality of a writing (Newmark, 2001) This belief, together with my own interesting findings about
ambiguities in English, prompted me to conduct the research titled Types of Ambiguity
in Writing English by Sophomore Students of English Education at Can Tho University
1.2 Research aims
The research aims at two goals First, it aims to investigate types of ambiguity sophomore students of English Education at Can Tho University (CTU) make when writing in English Second, on the basis of the findings, recommendations of resolving common types of ambiguities, and pedagogical implications will be proposed
1.3 Significance of the study
The primary aim of the study is to investigate types of ambiguity by sophomore English Education majors at CTU The study, first of all, thus creates a great learning
opportunities for the researcher to enhance (a) a deeper understanding of conducting research work and (b) deeply held knowledge of the research subject matter (i.e.,
ambiguity in English) through research activities (Feldman & Mc Phee, 2008) Second, the findings of the study raise awareness among EFL teachers and students at CTU of the current writing practices in term of writing errors, in particular, the ones including ambiguities Third, the inclusion of recommendation to resolve common types of ambiguity found in the study contributes a helpful guidance to improve the quality of the students’ writing

LITERATURE REVIEW
In this chapter, definitions of ambiguity will be first addressed Then ambiguity types and
an ambiguity test will be presented
2.1 Definitions of ambiguity
To describe and explain ambiguities in language is one of the goals of semantic theory (Zhang, 2007) Thus, many linguists have studied and defined the term
ambiguity in their own ways According to Bach (1994), ambiguity is a word, a
phrase, or a sentence having more than one meaning Clare (2003) states that something is ambiguous when it can be understood in two or more possible senses or ways Similarly, Jacobs (2003), To (2004) and Zhang (2007) define that ambiguity is open more than one interpretation or more than one possible meaning Newmark (2001) also defines that ambiguity, in the sense of a stretch of a second language text,
is normally a word or syntactic structure having apparently more than one meaning
in or in spite of its context It is obvious that these definitions of ambiguity are slightly different in the way they are stated, but not the nature ambiguity itself In
general, ambiguity is a phenomenon of having or expressing more than one possible meaning
There are three important points that not only linguists but also any language learners have to notice about ambiguities First, ambiguity is always concerned with meaning regardless of what type of ambiguity it is (Tran, 2006) Second, almost every word or expression or sentence, before realization of stress, stop, intonation or other phonological means and without any more presuppositions or contexts than what the word or the sentence itself creates, can be regarded as two or more different senses (Zhang, 2007) In other words, ambiguity exists only when a word or a phrase or a
sentence has at least two specific meanings that make sense in context Third,
ambiguity and vagueness should be differentiated from each other Though seemingly synonymous in common usage, they are entirely different but very important problems
in critical thinking This means although words that are vague and words that are
Trang 12ambiguous are hard to define without context and sometimes even with context, they are completely not the same (Payne, 2010) While ambiguity is a phenomenon of having at least two specific meanings that make sense in context, vagueness is concerned with any word or phrase that is not clear in context To be more clearly, words or phrases or sentences are considered vague when they are not specific enough
to clearly cover all cases That is to say, if someone doesn’t know what is meant by a
phrase, then that phrase is vague to him/her On the contrary, if he/she doesn’t know which of two or more specific meanings is intended by this phrase, then it is
According to Bach (1994), To (2004), Tran (2006) and Zhang (2007), there are two types of ambiguity: lexical and structural
(1) Lexical ambiguity is a phenomenon resulted from sentences which have more
than one meaning because of the polysemy or homonyms in these sentences
(Tran, 2006) Two good examples of this ambiguity type are (a) “That robot is bright” and (b) “She cannot bear children” In sentence (a), the adjective
“bright” is a polysemous word which has two slightly different but closely related meanings: shining and intelligent Therefore, the robot may be understood to be shining or intelligent Sentence (b) can be interpreted in two
different ways because the two verbs “bear 1” means “tolerate” and “bear 2”
means “give birth to” They are two homonyms that make the sentence logically ambiguous
(2) Structural ambiguity is the one that does not lie in the words but rests on two
or more possibilities of relationship of modification among words contained in the sentence (Zhang, 2007) In other words, structural ambiguity is a
Trang 13phenomenon resulted from sentences which have more than one meaning because the structures in these sentences can be interpreted in different ways (Tran, 2006) This ambiguity type occurs when a phrase or a sentence has more than one underlying structure (Bach, 1994) It is illustrated by two good
examples (a) “The chicken is ready to eat” (Bach, 1994) which could be used
to describe either a hungry chicken or a boiled chicken and (b) “Last week at the beach, I saw the man eating fish” (Tran, 2006) which can be understood to
be “to see the man who is eating fish” or “to see a kind of fish that eats man”
Codish and Shiffman (1995) classify ambiguities into 3 types: lexical, syntactic and pragmatic
(1) Lexical ambiguity is the “classic” form of ambiguity in which a
word can be interpreted in more than one way, such as the word “bank” in the sentence “I will meet you at the bank”
(2) Syntactic ambiguity is caused when the structure or the syntax of a statement is ambiguous This can occur when punctuation or connectors in
a statement leave its meaning unclear An example is “A or B and C” without clarifying whether this means “(A or B) and C” or “A or (B and C)”
(3) Pragmatic ambiguity occurs when two or more interpretations of
meanings are provided It refers to usage, as in saying on Wednesday: “See you next Friday” We do not know whether the speaker means to meet in
two days (i.e., this week’s Friday) or in nine days (i.e., next week’s Friday)
Newmark (2001) suggests that there are seven types of ambiguity
(1) Lexical ambiguity may result from words having many senses or
meanings
(2) Grammatical ambiguity, which is also called structural or
syntactic ambiguity, usually occurs within the context of a poorly written
sentence For example, both notorious ambiguous groups as “John’s
Trang 14book”, “slow neutrons and protons” and the less obvious ones as “modern language teaching” are considered good illustrations of this ambiguity
(3) Pragmatic ambiguity is similar in all language, provided that
they are relatively culture-free This ambiguity type is inevitably more common in written than in spoken language because the tone or the
emphasis in a second language is not clear The sense of “Goodnight” was widely understood as “Hello” or “Goodbye” when the day time is relevant
(4) Cultural ambiguity may arise if the function or the substance of
a cultural feature changes at a point of time and the term remains whilst the period background is not clear in the second language text
(5) Idiolectal ambiguity occurs when a word used inappropriately
and commonly in many situations although the users have never looked them up in a dictionary but have used them as a habit
(6) Referential ambiguity occurs when a sense of ambiguity prompts
two or more images of the reality which the translator is trying to describe (7) Metaphorical ambiguity can be found in most sentences that are
hard enough to be examined their meanings
Unlike Newmark (2001), Hoenisch (2004) classifies ambiguity into four types
(1) Lexical ambiguity is the result of words having more than one
possible meaning For example, the word bank in sentence “John went to the bank” causes lexical ambiguity because it provides two different meanings the edge of the river or the financial institution
(2) Syntactic ambiguity is the result of phrases or sentences that can be
understood in more than one way as in the example “put the box on the table in the kitchen” The sentence may be paraphrased as put the box on the table which is in the kitchen or take the box on the table and put it in the kitchen
(3) Local ambiguity is the one cleared up once we have heard or read the
whole sentence For example, the word “train” in “the old train” can be
considered to be “a means of transportation” or “guide” However, this
Trang 15phrase is not ambiguous once we hear or read the whole sentence “the old train left the station” or “the old train the young”
(4) Global ambiguity remains even after the entire sentence has been
heard or read The sentence “I know more beautiful women than Julia” is considered to be globally ambiguous because this could mean “I know women who are more beautiful than Julia” or “I know more beautiful women than Julia does” We hardly know which meaning this sentence
attempts to express even though we hear or read it carefully
According to Webber (2007), ambiguities are of three types
(1) Lexical ambiguity is defined as a word associated with more one part
of speech or with more than one sense
(2) Structural ambiguity is defined as a string of words associated with
more than one structure; and these structures are often represented by constituent structure trees
(3) Semantic ambiguity occurs when the same structures and word senses
can still have multiple interpretations This ambiguity type consists of Scope ambiguity and Referential ambiguity
(a) Scope ambiguity is defined as a word that can operate on the meanings
of other words and structures, and hence may produce ambiguity For
example, the word “not” in the following example “David did not take
the bus to the zoo” causes scope ambiguity because we can understand
that “He did not take the bus to the zoo but he drove there” or “He did not take the bus to the zoo but he took it to somewhere” or “He did not take the bus to the zoo but he stayed at home” In other words, different
scopes of negation cause different meanings
(b) Referential ambiguity occurs when a term can refer to several entities
of a sentence, so this sentence produces different interpretations The
sentence “David hid the keys of Fred’s car because he was drunk” is a
good example of this ambiguity type Considering the sentence, it’s hard
Trang 16for us to know whether “he” is David or Fred Therefore, he is a term
that makes the sentence to be referential ambiguous
As mentioned earlier, ambiguity is always concerned with meaning In addition, all of the linguists agree that although ambiguous words or ambiguous sentences can
be understood in many ways, the speaker of these has one meaning in mind That is, only one of meanings corresponds to what the speaker intends
Ambiguities resulted from meanings of words or expressions are called lexical ones, whereas structural ambiguities caused by a sentence which has more than one underlying structure, is called syntactic or grammatical In addition, a word which can
be more than one part of speech may result in both lexical and structural ambiguity
For example, sentences as (a) “Tom fed her dog biscuit” (Tran, 2006, p 40) and (b)
“We saw her duck” (Zhang, 2007, p 5) are considered to be ambiguous in terms of both lexical and structural because the word her may be an objective pronoun or a possessive adjective Therefore, sentence (a) can be understood as “Tom gave dog biscuit to her” or “Tom gave biscuit to her dog” Similarly, sentence (b) can be interpreted as “We saw her quickly lower her head” or “We saw the duck of hers” It is
thus hard to draw a clear line between lexical and structural ambiguities if these two terms coexist in one sentence (Newmark, 2001)
Although referential ambiguity is not always mentioned by these linguists, it is serious and pertinent to be solved because we hardly interpret the sentence accurately
if it is referentially ambiguous (Webber, 2007) Like referential ambiguity, local and global ones are not paid much attention by language users though they obviously exist
in all languages (Hoenisch, 2004) Scope ambiguities are mostly resulted from two
elements The first is an adverb of frequency followed by two verbs as always eat pies and refuse milk (Nguyen & Huynh, 2008) in which always may modify eat or both eat and refuse The second is negative words in a sentence as no, not, hardly which may
make the sentence ambiguous because no one knows which of the parts in a sentence
or even the whole sentences is negated, so different scopes of negation also cause ambiguity (Webber, 2007) In addition, although scope ambiguity type does not
Trang 17usually result in serious problems to users, it is very difficult for them to avoid because they cannot always produce affirmative sentences It is also hard to disambiguate an ambiguous negative sentence since such sentence usually consists of several parts Therefore, we hardly know that the negative word attempts to negate whether one part or whole sentence
Lexical ambiguous sentences after being added more context to be
disambiguated are locally ones, as sentence She cannot bear children is lexical ambiguity; however, once it is added because children are noisy, it becomes a locally ambiguous sentence because the word bear means tolerate To be specific, the whole sentence She cannot bear children because they are noisy is not lexical but local
ambiguity because the meaning of this sentence is clear once we read the whole sentence Since both local and global ambiguous sentences are considered to be ambiguous or disambiguous only when we finish hearing or reading the whole sentence, both of them can simultaneously be any other types of ambiguity such as structural, lexical, referential, scope and so on
How to identify and resolve ambiguity even though it is so complex and hard is very important to language users Kempson (1996) designed an ambiguity test which suggests principles to help language users test whether or not a sentence is ambiguous The ambiguity test will be introduced in the next section
2.3 An ambiguity test
An ambiguity test is the one which helps to distinguish between sentences which are ambiguous and sentences which are not, and helps to separate out cases of vagueness from cases of ambiguity, and which will give us some basis for deciding on the less clear cases (Kempson, 1996)
Since ambiguities are usually hard to identify, language users should examine any phrase or sentence carefully before determining them to be ambiguous In order to distinguish sentences which are ambiguous from sentences which are not, we should examine carefully the processes which refer back to an earlier part of the sentence For
Trang 18example, the expression “to do so too” in “John killed a bird today and so did Susie” (Kempson, 1996, p 131) leads to the meaning that “Not only John but also Susie killed a bird today”, so this sentence is not ambiguous In contrast, this expression in the sentence “Terry loves his wife and so do I” (Nguyen & Huynh, 2008, p 12) causes ambiguity because we hardly know for sure that whether “I also love Terry’s wife” or
“I also love my wife” Thus, two sentences which have the same structure are not
always simultaneously ambiguous (Kempson, 1996) This principle is good for both language learners and users to identify ambiguities and differentiate them from non-ambiguous cases
As mentioned in section 2.1, ambiguity and vagueness confuse learners although they are not identical Therefore, we should be certain of separating out cases of vagueness from cases of ambiguity In order to distinguish ambiguity from vagueness,
we have to find how many meanings the words or sentences provide If there is more than one meaning in them, this is concluded that there is some ambiguity in the words
or sentences In contrast, if we do not know what meaning these words or sentences
attempt to express, this is a case of vagueness For example, “She likes xxx” is vague because no one knows what she likes, person or thing or flower, while “We watched the hunters with binoculars” is structurally ambiguous because “with binoculars” is either an adjective phrase to be the post-nominal modifier of the noun phrase the hunters or an adverb phrase to be the optional adjunct of means of the verb watched
In summary, ambiguity deals with a variety of interpretations in meanings Regardless of how many meanings which are interpreted, there is only one precise meaning that is intended by the speaker or writer Ambiguities are classified into a number of classifications (i.e., lexical, structural, scope, referential, local, global, pragmatic, cultural, idolectal, metaphorical) However, lexical, structural, scope and referential ambiguities are more popular, and more pertinent to be disambiguated (Newmark, 2001; Jacobs, 2003) Thus, these four ambiguity types will be analyzed and reported in the chapter of research results These ambiguity types are defined
shortly as (1) lexical ambiguity is caused by homonyms or polysemy in a sentence, (2)
structural ambiguity occurs when a structure has more than one underlying
Trang 19interpretation, (3) referential ambiguity is resulted from a word which may refer to more than one term of a sentence, and (4) scope ambiguity usually occurs in sentences which consist of adverb of frequency followed by two verbs, or negative words Since
ambiguous sentences resulted from words which can be more than one part of speech are both lexical and structural, the researcher considers these sentences lexical ambiguity so that it is easier to classify ambiguity types found from the results of research instrument In the procedures of identifying ambiguities, the researcher employs the ambiguity test by Kempson (1996) to collect all of ambiguities in terms
of lexical, structural, referential and scope

CHAPTER 3
RESEARCH METHODOLOGY
This chapter will present the research method employed in this study There are six parts in this chapter: research questions, the researcher’s hypotheses, research design, participants, research instruments, and procedures of test administration
3.1 Research questions
This research is guided by two research questions:
(1) Do sophomore students of English Education CTU make ambiguities when they are
writing in English?
(2) What types of ambiguity are made by the students?
3.2 Hypotheses
Basing on the related literature and the research questions, the researcher hypothesizes
that (a) sophomore TEFL majors at CTU would make ambiguities in writing in English, and (b) more structural and scope ambiguities would be made than referential and lexical
3.4 Participants
29 English Education majors course 34 at CTU were invited to participate in this research Their ages are commonly from 20 to 21 One of them has studied English for 11 years, 27 studied have studied English for 9 years and only one has studied English for 5 years
