English for specific purposes (ESP)

English for specific purposes (ESP) has for about 30 year been a separate branch of English language Teaching.it has developed its own approaches , materials and methodology and is generally seen as a very active, even ' feisty' movement that has had considerable influence over the more general activities of TESOL  and applied linguistics.
1) ESP  is designed to meet the specific needs of the learners.
2) ESP makes use of the underlying methodology and activities of the discipline it serves.
3) ESP is centerd on the language ( grammar ,lexis, register) , skills, discourse and genres appropriate to these activities ( Dudley-  Evans And st John 1998 )
ESP is material led field.most materials, however , are prepared by individual teachers for particular situations and there is not a huge amount of published ESP material.Hamplyons discusses a number of coursebooks in EAP.
