Have the idea the price is a quid (4)
I believe the answer is:
feel
'have' is the definition.
(thesaurus)
'idea the price is a quid' is the wordplay.
I cannot really see how this works, but
'price' could be 'fee' (price paid for a service) and 'fee' is present in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'the' is the link.
Can you help me to learn more?
(Other definitions for feel that I've seen before include "Have a belief; touch" , "Perceive, sense" , "16A [JUDGE]" , "Instinct" , "Perceive by touch" .)
