Food market, we hear? (4)
I believe the answer is:
fare
'food' is the definition.
(fare is a kind of food)
'market we hear?' is the wordplay.
'market' becomes 'fair' (I've seen this in other clues).
'we hear?' shows a homophone (sound like).
'fair' sounds like 'FARE'.
(Other definitions for fare that I've seen before include "Food provided in fear" , "Charge for journey" , "Cost of travel" , "Payment for journey" , "Price of passage" .)
