My question is not very serious, but I'd like to know what the contraction ain't means. I met it in the song of Chris de Burgh, 'Moonlight and roses'. 'Tonight there's a band, it ain't such a bad one / Play me a song, don't make it a sad one.'
You are right, Julia. 'It ain't' here could be re-written in standard English as 'it isn't' or 'it's not'.
'Ain't' is non-standard English, but is quite common in dialects and in colloquial forms of British and American English. So it is important to be able to recognise it, but not so important to be able to produce it in speech or writing. It is used as the contracted form of a number of different aspects of the verbs and auxiliary verbs 'to be' and 'to have', so it is quite useful, as you can see. It is the contracted form of:
It is often used with a second negative in the same clause, producing a double negative, which is ungrammatical, but quite normal in this variety of English:
'You ain't goin' nowhere. You're stayin' right here.'
'I ain't done it yet. No. I ain't 'ad a minute to meself.' (= myself).
'I ain't Superman.'
'It ain't right for Joan to tell Jane what to do.'
'He still ain't returned that bike. How long's he 'ad it for now?'
'You ain't finished your supper, Simon. Ain't you 'ungry, or what?'
'It ain't arf 'ot in 'ere.'
The standard negative contractions of these two verbs, which you should be using, particularly in speech and in informal writing, are as follows. There are quite a few of them, as you can see. Note that he's not is the standard contracted form for both 'he has not' and 'he is not'. Note also that 'am not' is normally contracted to 'aren't' only in questions.
