Card game with melds (7)
I believe the answer is:
canasta
'card game with melds' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for canasta that I've seen before include "Form of rummy using two decks of cards and four jokers" , "this needs two packs" , "Game played with two packs of cards and jokers" , "series of hands" , "Card-game, a form of rummy" .)
