Thanksgiving guests, often (3)
I believe the answer is:
kin
'thanksgiving guests often' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for kin that I've seen before include "Relations, go with kith" , "Family and relations" , "Relatives, family" , "Connections; family" , "Relatives from Kinnegad" .)
