Serviette (6)
I believe the answer is:
napkin
'serviette' is the definition.
(I know that serviette can be written as napkin)
This is the entire clue.
(Other definitions for napkin that I've seen before include "Cloth to stop, eg, gravy" , "piece of material giving consumer protection" , "Protective cloth square worn at meal" , "Cloth rectangle worn at mealtime" , "Cloth square worn while eating" .)
