A, B & C Languages, and Combinations

A Language. The interpreter's native language (or another language strictly equivalent to a native language), into which the interpreter works from all her or his other languages in both modes of interpretation, simultaneous and consecutive.

B Language. A language other than the interpreter's native language, of which she or he has a perfect command and into which she or he works from one or more of her or his other languages. Some interpreters work into a "B" language in only one of the two modes of interpretation.

C Language. The language(s) of which the interpreter has a complete understanding and from which she or he works. Interpreters often have several C languages.

Language Combination. An interpreter's language combination is comprised of his/her A, B and/or C languages. The interpreter can be recruited on the basis of active languages (spoken) and passive languages (listened to) used during the conference.
