Which statement best describes simultaneous bilingual development?

• A. The statement is true: vocabulary grows across both languages and code-switching is common.
• B. Vocabulary grows across both languages, but code-switching is never observed.
• C. Vocabulary grows only in the dominant language.
• D. Bilingualism always leads to confusion.

Answer: (B)

Simultaneous bilingual development means a child is exposed to two languages from birth and builds proficiency in both. In this pattern, vocabulary grows in both languages because each language is used in different contexts and with different speakers. Code-switching—mixing words from both languages in the same utterance—is common among simultaneous bilinguals and is a normal way they navigate two linguistic systems. It often helps them express meaning more precisely when one word is easier to find in one language or when the conversation partner switches to a different language. The idea that vocabulary would only grow in the dominant language or that bilingualism causes universal confusion doesn’t fit typical development. So the most accurate view is that children learn vocabulary in both languages and frequently switch between them as needed.
