Last of home gatherings (5)
I believe the answer is:
omega
'last' is the definition.
(thesaurus)
'of home gatherings' is the wordplay.
'of' says the answer is hidden in the clue.
'OMEGA' is hidden within 'home gatherings'.
(Other definitions for omega that I've seen before include "End of sequence" , "Athenian character" , "16 letter" , "Consummation" , "Last thing" .)
