This question already has an answer here:
Some sentences have a double 'is' in them.
I know that we must have the verb to be in a nominal sentence, but these sentences have a double 'is'.
Can anyone tell me which 'is' acts as the verb to be as part of the nominal sentence - and therefore whats the grammar of the other 'is'?
'What it is is a legal device which confirms the working of a release from debt which would otherwise be invalid.'
(This example was taken from the BNC online language corpus)
Here's two examples that I would hear in Britain:
'Why don't you take the job?'
'Well, what it is is that I hate dealing with customers.'
'What's this strange machine?'
'Well, what it is is a new type of coffee maker.'
