I'm a little stuck... Click here to teach me more about this clue!

'a breath and pay?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'so take' is the wordplay.
I cannot really see how this works, but
'so' could be 'then' (I've seen this before) and 'then' is found in the answer.
'take' could be 'r' (abbreviation for 'recipe', Latin for 'take') and 'r' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
