A vocabulary is the set of words in a language or known by an individual person, and it comes from a Latin word meaning "a word, name." It's essential for communication because it allows people to express their thoughts, ideas, emotions, and information through spoken, written, or signed language, and can be divided into active vocabulary (words you use regularly) and passive vocabulary (words you recognize but don't use often).

A vocabulary (also known as a lexicon) is a set of words, typically the set in a language or the set known to an individual. The word vocabulary originated from the Latin , meaning "a word, name". It forms an essential component of language and communication, helping convey thoughts, ideas, emotions, and information. Vocabulary can be oral, written, or signed and can be categorized into two main types: active vocabulary (words one uses regularly) and passive vocabulary (words one recognizes but does not use often). An individual's vocabulary continually evolves through various methods, including direct instruction, independent reading, and natural language exposure, but it can also shrink due to forgetting, trauma, or disease. Furthermore, vocabulary is a significant focus of study across various disciplines, like linguistics, education, psychology, and artificial intelligence. Vocabulary is not limited to single words; it also encompasses multi-word units known as collocations, idioms, and other types of phraseology. Acquiring an adequate vocabulary is one of the largest challenges in learning a second language.
== Terminology == A vocabulary is the set of words in a given language that an individual knows and uses. In the context of linguistics, a vocabulary may refer more broadly to any set of words. Types of vocabularies have been further defined: a lexis is a vocabulary comprising all words used in a language or other linguistic context or in a person's lexical repertoire. An individual person's vocabulary includes a passive vocabulary of words they can recognize or understand, as well as an active vocabulary of words they regularly use in speech and writing. In semiotics, vocabulary refers to the complete set of symbols and signs in a sign system or a text, extending the definition beyond purely verbal communication to encompass other forms of symbolic communication.
