stay

stay: English has three distinct words stay, two of them ultimately from the same source. Stay ‘stop’ [15] comes from estai-, the present stem of Old French ester ‘stand, stop’. This in turn went back to Latin stāre ‘stand’ (source of English state, statue, etc). Staid [16] originated as the past participle of stay. Stay ‘strong rope’ [OE] comes from a prehistoric Germanic *staga-. This was derived from a base *stagh-, *stakh- ‘be firm’, which also produced English steel and (by borrowing) Old French estayer ‘support’ (source of English stay ‘support’ [16]).
