A linguist can be several things, but in any sense a linguist is a person who is skilled in some way with a given language, including ancient languages. The term linguist can be used to describe a person who specializes in linguistics, which is the study of language, or a linguist can be a person well versed in the translation, interpretation, and application of a language. Simultaneously, a linguist may also be a person who is fluent in multiple languages.

In the academic sense, a linguist is a person who engages in and studies linguistics. Simply put, linguistics refers to the scientific study of language – both theoretical and practical. A person studying or professionally practicing either theoretical or applied linguistics is said to be a linguist.

Examples of theoretical linguistics include grammar, syntax, semantics, origin, and phonetics. Applied linguistics encompasses practical utilization of the knowledge of a language, such as an interpreter, translator, a speech therapist, or a language teacher or professor.

Though the spoken word and written word often intertwine, a linguist focuses more on the spoken word than the written word. A polyglot, or person skilled in multiple languages, for example, could be considered a linguist. A person skilled in the written word may be considered a linguist, but would more so depend on the length and depth of his or her area of study in linguistics.

There is often some distinction made between linguists themselves, but in the ordinary sense of explanation a linguist is any person who is highly educated in both the practical and theoretical elements of one or more given language. There are both associations and professional organizations where a linguist may affiliate with other specialists who share their interests. One such organization is the Chartered Institute of Linguists, which publishes their own magazine titled The Linguist.

A linguist differs from a lexiphile, a modernly applied term for someone who loves words, because a linguist is learned in an entire language and not just specific words and has more theoretical knowledge of a language than just an expansive vocabulary. For those who are more than casually interested in both words and language but not as a course of study, check out KPBS Radio, 89.5 FM in San Diego, which broadcasts a live radio show titled A Way With Words. The show explores many aspects of the English language including grammar and origins and the use of specific words and phrases are discussed as well.
