Speak drunkenly (4)
I believe the answer is:
slur
'speak drunkenly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for slur that I've seen before include "Aspersion - speak indistinctly" , "Slight lack of distinction in speech" , "Negative comment" , "Disparaging comment" , "become inarticulate" .)
