no

\ \ English has three words no, which come from quite distinct sources (although they all, of course, contain the ancient negative particle ne). No the negative reply [OE] means etymologically ‘not ever, never’. It originated as a compound of ne and ā ‘ever’ (a relative of archaic modern English aye ‘ever’, whose own negative form is nay [12]) and the resulting nā became in the 13th century no. The history of no ‘not’ [OE] (which is now used virtually only in the expression ‘whether or no’) is almost exactly parallel: it was formed from Old English ō ‘ever’, a variant of ā. The adjective no ‘not any’ [13] is a reduced form of none, its final n originally dispensed with before consonants.
