Short definition
In interpreting, an active language is any language an interpreter interprets into actively – meaning productively and with full linguistic command.
Detailed explanation
The distinction between active and passive language is fundamental to how conference interpreters work. An active language is one in which the interpreter can not only understand but also formulate fluently, precisely, and stylistically well. This typically includes the A-language (native language) and, where applicable, the B-language.
This categorization directly affects how tasks are divided within an interpreting booth. If an interpreter only understands a language passively – meaning they comprehend it but can't reliably interpret into it – that language won't be used as a target language. This protects the quality of the interpretation.
When planning multilingual conferences, precise knowledge of each interpreter's active languages is essential. It determines which language combinations can be covered, how many booths are needed, and whether relay interpreting is required.
Relevance in this subject area
The active language is a key planning criterion for multilingual events. It affects team size, the number of booths, and the transmission technology required.
Practical example
An interpreter with German as their A-language and English as their B-language has two active languages. They interpret from French (a passive language) into German and English – but not into French.
