Intimate spotted taking a pee (5)
I believe the answer is:
imply
'intimate' is the definition.
(thesaurus)
'spotted taking a pee' is the wordplay.
'spotted' becomes 'pimply'.
'taking' suggests deleting specific letters.
'a pee' becomes 'p'.
'pimply' with 'p' removed is 'IMPLY'.
(Other definitions for imply that I've seen before include "Intimate, suggest indirectly" , "Indicate indirectly" , "Hint, suggest" , "Indicate by suggestion" , "Mean" .)
