Violent character, though mostly sheepish? (5)
I believe the answer is:
rambo
'mostly sheepish?' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'violent character' is the wordplay.
I cannot really see how this works, but
'character' could be 'r' and 'r' is found in the answer.
The remaining letters 'ambo' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'though' acts as a link.
Can you help me to learn more?
(Other definitions for rambo that I've seen before include "Stallone's he-man" , "Tough man (films)" , "Stallone tough guy" , "Character relying on brute force" , "Stupidly aggressive type" .)
