 L2 - Second Language; Foreign Language: The language a person knows, is learning or is acquiring in addition to their native language (L1 ). This is a key term if you need to cut down the word count in your writing; "L2 classrooms" is 37 characters shorter than "second language and/or foreign language classrooms". Also see SLA  and ESL  for additional information. |  |  |
