Brief sleep with English scruff (4)
I believe the answer is:
nape
'scruff' is the definition.
(synonyms)
'brief sleep with english' is the wordplay.
'brief sleep' becomes 'nap' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'english' becomes 'e' (abbreviation).
'nap'+'e'='NAPE'
(Other definitions for nape that I've seen before include "sofa" , "It's a pane in the neck" , "Scrag" , "Girl personifying France" , "Scruff of the neck" .)
