If they are going abroad for a short time to study English, they need to choose which country. For those staying at home, the choice may be made for them in that private language schools or the state school system may only offer one model. Students studying EFL in Hong Kong, for example, are more likely to learn British English, whereas students in the Philippines are more likely to learn American English. For this reason, many teachers now emphasize teaching English as an international language (EIL), also known as English as a ­lingua franca (ELF). Linguists are charting the development of international English, a term with contradictory and confusing meanings, one of which refers to a decontextualised variant of the language, independent of the culture and associated references of any particular country, useful when, for example, a Saudi does business with someone from China, or Albania.
