Which term is the language a person is learning or has learned as a second language?

• A. L1
• B. Interlanguage
• C. Calp
• D. Language 2

Answer: (D)

The key idea is the labeling of languages in second language acquisition. L1 is the native language you already know. The language someone is learning as a second language is called Language 2 (often written as L2). Interlanguage describes the learner’s evolving internal system as they progress toward the target language, not the language being learned itself. Calp isn’t a standard term in this context. So, Language 2 is the best fit because it directly names the second language, distinguishing it from the first language and from the learner’s developing interlanguage.
