Origin & History of “contact”

The underlying notion of contact is not surprisingly one of ‘touching’. It comes ultimately from Latin tangere ‘touch’, source of English tactile, tangent, and tangible. Using the prefix com- ‘together’ this was formed into a compound verb contangere ‘touch, border on’, whose past participle contāctus was borrowed into English, originally as a noun (its use as a verb is a surprisingly late development, which did not happen until the late 19th century). also derived from Latin contangere is contagion (14th c.), and contaminate is probably related.
