Warm-hearted love from a sweep, perhaps (3)
I believe the answer is:
oar
'a sweep perhaps' is the definition.
(sweep is a kind of oar)
'warm-hearted love' is the wordplay.
'warm' becomes 'o' (I can't explain this - if you can you should give a lot more credence to this answer).
'hearted' means to look at the middle letters.
'love' becomes 'endearment'.
The middle letters of 'endearment' are 'ar'.
'o'+'ar'='OAR'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for oar that I've seen before include "propellor" , "Use it to move a boat" , "Rower" , "Rowing device" , "Rowing boat operator" .)
