English for specific purposes (ESP) is a subset of English as a second or foreign language. It usually refers to teaching the English language to university students or people already in employment, with reference to the particular vocabulary and skills they need. As with any language taught for specific purposes, a given course of ESP will focus on one occupation or profession, such as Technical English, Scientific English, English for medical professionals, English for waiters, English for tourism, etc.1 Despite the seemingly limited focus, a course of ESP can have a wideranging impact, as is the case with Environmental English.
