Tape over head (4)
I believe the answer is:
pate
'head' is the definition.
(thesaurus)
'tape over' is the wordplay.
'over' indicates anagramming the letters.
'tape' anagrammed gives 'PATE'.
(Other definitions for pate that I've seen before include "Posh 8" , "loaf" , "Meat paste, perhaps de foie gras" , "Savoury paste; head" , "Tape for a head" .)
