Pricey fare, through having stopped taxi for one (6)
I believe the answer is:
caviar
'pricey fare' is the definition.
'caviar' can be an answer for 'fare' (caviar is a kind of food). I am not certain of the 'pricey' bit.
'through having stopped taxi for one' is the wordplay.
'through' becomes 'via' (via means going through).
'having stopped' indicates putting letters inside (stopping can mean blocking a gap).
'taxi for one' becomes 'car' (taxi is a kind of car).
'via' put inside 'car' is 'CAVIAR'.
Can you help me to learn more?
(Other definitions for caviar that I've seen before include "Sturgeon eggs" , "posh meal" , "Sturgeon delicacy" , "Sturgeon's roe" , "... prized delicacy" .)
