Conjunct is from Latin coniunctus, past participle of coniungere ('to join together'), from con- ('together') + iungere ('to join'), from a root meaning 'to yoke'. The ancestry passes through Latin coniungere, Latin iungere, and Proto-Indo-European *yewg-. The prefix con- adds togetherness, combination, or intensification where the Latin formation gives it that value, helping to explain the word's surface structure. In present use as adjective and noun, it means "joined or associated together; combined", keeping the historical formation close to the word's ordinary semantic work. Related words include conjunction, conjunctive, junction, conjoin, and disjunct; derived forms include conjunctly.
