    Note

    The broadest meaning, and an old one. Middle English cosin could name almost any relative: a nephew or niece, a grandchild, even a godparent. The loose sense lasted well beyond that. In Shakespeare's Much Ado About Nothing a man asks his brother after "my cousin your son," where a modern speaker would say nephew.

    Similarrelative, relation, sibling

    Note

    The family word stretched to cover things, and it can sit before a noun like an adjective: Spenser's The Faerie Queene (1590) calls sorrow and wrath "coosen passions," and Joshua Sylvester's early 17th-century translation of Du Bartas has "Cozen-swords." The phrase next cousin to means "very nearly the same as": Edward Topsell in 1607 calls a bad bodily habit next cousin to dropsy. Institutions qualify too, as when the Mossad is called the CIA's cousin.

    nouncountable

    Pull up a chair, cousin, and tell me everything.

    Note

    Here kinship is lent as a mark of familiarity. In older fiction it also pairs with my and a description, as in Walter Scott's "my cousin the weaver" or Henry Fielding's "my dirty Cousin." In those cases the tone is rough, teasing or quarrelsome rather than affectionate, so listen for that edge before reading every instance as warmth.

Origin

The noun comes from Middle English cosin ("a relative or kinsman"), which came through Anglo-Norman and Old French cosin/cosine from Latin cōnsobrīnus ("maternal cousin; relation"), possibly via a Vulgar Latin form. This was built from con- plus sobrīnus ("maternal cousin"), tracing ultimately back to the Proto-Indo-European word for "sister." The verb is derived from the noun.
