I know I can't send coin without my passphrase, but I have forgotten it. All I would like to know is, is the passphrase a phrase I come up with? Or does Bitcoin Core provide the phrase? Many thanks.
Also is it just one word or a sequence of words?

It is used to encrypt the wallet so that only you can use it.

It is up to you what characters to type and whether it includes spaces.
The program suggests "Please use a passphrase of ten or more random characters, or eight or more words" So, if you are the sort of person to heed advice, you probably chose a passphrase following one or the other of those forms.
I have forgotten it.
