Caution a looker about Scots man (8)
I believe the answer is:
admonish
'caution' is the definition.
(synonyms)
'a looker about scots man' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is present in the answer.
'man' could be 'm' and 'm' is located in the answer.
The remaining letters 'dish' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for admonish that I've seen before include "Chide or reprimand" , "Reprove, take to task" , "Reprove, warn" , "Scold, wag the finger at" , "Chide, reprove" .)
