Holding a butt and a bit bleary in the five o'clock shadow (7)
I believe the answer is:
stubble
'the five o'clock shadow' is the definition.
(I've seen this in another clue)
'holding a butt and a bit bleary' is the wordplay.
I cannot really understand how this works, but
'butt' could be 'stub' (synonyms) and 'stub' is present in the answer.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for stubble that I've seen before include "Remains of corn" , "Unshaven growth on the face" , "Short whiskers" , "Short stiff growth of beard" , "Cut cereal stalks" .)
