Provides food inside before corgi gets upset (6)
I believe the answer is:
grocer
'provides food' is the definition.
I can't judge whether this definition defines the answer.
'before corgi gets upset' is the wordplay.
'gets' indicates a hidden word.
'upset' is a reversal indicator.
'recorg' can be found hidden inside 'before corgi'.
'recorg' reversed gives 'GROCER'.
'inside' is the link.
Can you help me to learn more?
(Other definitions for grocer that I've seen before include "One supplying households" , "Provision merchant" , "Retailer of food and small household goods" , "Market trader" , "Shopkeeper selling food" .)
