versed

Versed is an adjective meaning experienced, knowledgeable, or skilled in a particular area. It is most commonly used with in, as in well versed in diplomacy or versed in mathematics. The compound adjective well-versed is widely used, and when placed before a noun it is typically hyphenated (a well-versed historian). The sense is figurative rather than poetic.

Historically, versed is the past participle of the verb verse, which in older English meant to turn prose into verse or to compose verse. That verb sense is now rare, and the modern meaning of versed derives from being familiar with or practiced in a subject. The negative counterpart is unversed, meaning lacking knowledge or experience.

Usage notes: In contemporary English, well-versed in is the standard way to express competence. Using versed without a modifier is less common and can sound archaic or literary. In formal or academic writing, readers expect the familiar collocation well-versed (in X); in more casual contexts, synonyms such as knowledgeable or experienced are often preferred.

Examples: She is well versed in constitutional law. He is versed in several regional dialects of the language. While historically one might encounter phrases like “the poet versed in ancient meters,” such usages are largely confined to literary or historical contexts today.
