- Ont, Ont., TNO, ton
From Middle English not, nat, variant of noght, naht ( “not, nothing” ), from Old English *nōht, nāht ( “nought, nothing” ), short for nōwiht, nāwiht ( “nothing”, literally “no thing, no creature” ), corresponding to nā ( “no” ) + wiht ( “thing, creature” ). Cognate with Scots nat, naucht ( “not” ), West Frisian net ( “not” ), Dutch niet ( “not” ), German nicht ( “not” ). Compare nought and aught. More at no, wight .
In modern usage, the form do not ... ( or don’t ... ) is preferred to ... not for all but a short list of verbs ( is/am/are/was/were, have/has/had, can/could, shall/should, will/would, may/might, need ):
