Pretty well reduced at the end (4)
I believe the answer is:
cute
'pretty' is the definition.
(both can mean attractive)
'well reduced at the end' is the wordplay.
'well reduced' becomes 'cut' (similar in meaning. I am not sure about the 'well' bit.).
'at' is a charade indicator (letters next to each other).
'end' indicates one should take the final letters.
The final letter of 'the' is 'e'.
'cut'+'e'='CUTE'
Can you help me to learn more?
(Other definitions for cute that I've seen before include "Astute - lovely" , "Shrewd" , "Attractive and quaint (4" , "Smart" , "winning" .)
