What term describes learning a second language without losing the first?

• A. Additive bilingualism
• B. Subtractive bilingualism
• C. Monolingualism
• D. Diglossia

Answer: (A)

Learning a second language while keeping the first intact is additive bilingualism. This term describes adding another language to your repertoire without losing your existing one, often supported by environments or education that value maintaining both languages. It contrasts with subtractive bilingualism, where acquiring a second language coincides with losing or greatly diminishing the first. Monolingualism is about using a single language, not about adding another. Diglossia refers to different languages or varieties used in separate social contexts, not specifically about the process of language acquisition and maintenance. So, the best term for learning a second language without losing the first is additive bilingualism.
