connector (n.)

mid-15c., "to join, bind, or fasten together," from Latin conectere "join together," from assimilated form of com "together" (see con-) + nectere "to bind, tie" (from PIE root *ned- "to bind, tie").

Displaced 16c. by connex (1540s), from French connexer, from Latin *connexare, a supposed frequentative of conectere (past participle stem connex-). Connect was re-established from 1670s.

A similar change took place in French, where connexer was superseded by connecter. Meaning "to establish a relationship" (with) is from 1881. Slang meaning "get in touch with" is attested by 1926, from telephone connections. Meaning "awaken meaningful emotions, establish rapport" is from 1942. Of a hit or blow, "to reach the target," from c. 1920. Related: Connected; connecting; connectedness.
