Using Vocabulary well

A closer look at how vocabulary is used — meaning in plain English, how close synonyms differ, and examples at different levels.

Meaning in everyday English

The whole set of words a person knows or that belong to a particular language or subject.

When to use it

Use it to talk about the range of words available to a person, a language, or a field. It works in education, writing, and specialized or technical discussion.

Common context

Language learning, education and testing, technical fields ('legal vocabulary'), and figurative use for a set of available elements ('a designer's visual vocabulary').

Watch out

Do not confuse 'vocabulary' (the words themselves) with 'grammar' (the rules for combining them); knowing many words is not the same as arranging them correctly.

Synonyms by tone or intensity
lexicon
More formal and scholarly; often means the full word-stock of a language or field, and can also name a dictionary.
wordstock
Plain and somewhat old-fashioned; a direct native-English label for the body of words a language has.
terminology
Narrower; the specialized terms of a particular subject rather than someone's general word knowledge.
diction
Shifts focus to word choice and its effect in speech or writing, not the stock of words known.
Examples by level
  • Beginner Reading every day helped me build a bigger vocabulary.
  • In writing The report used the precise vocabulary of finance, so casual readers needed a glossary to follow it.
  • Advanced Each architect works within an inherited vocabulary of forms, and originality lies less in inventing new words than in combining the old ones unexpectedly.
Memory tip

'Vocabulary' shares a root with 'vocal' and 'voice' (Latin 'vox') — the words you have a voice for.
