tense: English has two separate words tense. The older, ‘verb form indicating time’ [14], came via Old French tens from Latin tempus ‘time’ (source also of English temporal, temporary, etc). The original meaning ‘time’ survived into English, but died out in the early 16th century. The adjective tense [17] was adapted from tensus, the past participle of Latin tendere ‘stretch’ (source also of English tend, tendency, etc). It originally meant simply ‘stretched tight’, and the metaphorical ‘strained’ did not emerge until the 19th century. Tension [16] comes from the Latin derivative tensiō. => temporary; tend
