The vocabulary of a language is known as which of the following?

• A. Lexicon
• B. Semantics
• C. Phonology
• D. Morphology

Answer: (A)

The main idea here is what we call the lexicon. The lexicon is essentially the set of all words a language has and the information speakers know about them—meanings, how they’re pronounced, their parts of speech, and how they inflect or combine with other words. Semantics studies meaning itself, including how words relate and how truth conditions work. Phonology looks at sound patterns and how sounds are organized in the language. Morphology examines how words are built from roots with prefixes and suffixes. So the vocabulary of a language is best described as the lexicon.
