Definition

Noun: 1. The total vocabulary of a language: The complete set of words and word forms, including all inflections and derivations, that exist within a particular language. 2.

Usage

• Lexis is a technical term used primarily in linguistics and language studies. It refers to the entire stock of meaningful units in a language's vocabulary, as opposed to its grammar or syntax.
• It is often discussed in contrast with grammar. While grammar deals with the rules and structures for combining words, lexis deals with the words themselves.
• It can be analyzed at different levels, such as the general lexis of English, the specialized lexis of legal documents, or the personal lexis of a particular author.

Examples

• Linguists study the lexis of Old English to understand how the language has evolved.
• The technical lexis of computer programming includes terms like "algorithm," "syntax," and "variable."
• A poet's distinctive lexis contributes to their unique style and voice.
• The report noted a shift in the political lexis, with new terms like "net-zero" becoming commonplace.

Advanced Usage

• Lexical Field/Semantic Field: A group of words related by meaning (e.g., the lexical field of "cooking": ).
• Lexical Item: A single unit of vocabulary, which can be a word, a compound word, or a multi-word expression with a single meaning (e.g., "post office," "kick the bucket").
• Lexical Density: A measure of the proportion of content words (nouns, verbs, adjectives, adverbs) to grammatical words (prepositions, conjunctions, articles) in a text.
