Place for a napkin (3)
I believe the answer is:
lap
'place for a napkin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lap that I've seen before include "Scoop up with the tongue" , "Drink; lick" , "place for small computer?" , "One complete circuit" , "One circuit of a course" .)
