If it isn't in Collins dictionary it won't be allowed.

If you are playing by official rules then it needs to be an official Scrabble word.

I have just gone on to the Collins dict. site --it is there---and yet not allowed if I go on the official Scrabble site----still confused!

[cashier]

I think it is only used in a phrase such as status quo or quid pro quo, not able to be used on it's own.
