See drunkard outside front of pub (4)
I believe the answer is:
spot
'see' is the definition.
(thesaurus)
'drunkard outside front of pub' is the wordplay.
'drunkard' becomes 'sot' ('sot' can be a synonym of 'drunkard').
'outside' means one lot of letters goes inside another.
'front of' indicates taking the first letters.
The initial letter of 'pub' is 'p'.
'sot' going around 'p' is 'SPOT'.
(Other definitions for spot that I've seen before include "Notice - place" , "Dot, stain" , "Small mark; observe" , "Lady Macbeth: ''Out, damned . . . .!''" , "Difficult situation" .)
