After half an hour I send food round to feed (7)
I believe the answer is:
nourish
'feed' is the definition.
(I've seen this before)
'after half an hour i send food round' is the wordplay.
'after' is a charade indicator (letters next to each other).
'half an hour' becomes 'ur'.
'send food' becomes 'nosh' (I can't explain this - if you can you should give a lot more credence to this answer).
'round' means one lot of letters goes inside another.
'ur' put next to 'i' is 'uri'.
'uri' placed inside 'nosh' is 'NOURISH'.
'to' is the link.
Can you help me to learn more?
(Other definitions for nourish that I've seen before include "Feed, sustain" , "I rush on (anag.)" , "Provide with food for growth" , "support" , "Provide with materials for life and growth" .)
