Embellish pack of cards (4)
I believe the answer is:
deck
I believe this clue is a triple definition!
'embellish' is the first definition.
(both can mean to decorate)
'pack' is the second definition.
(deck is a kind of pack)
'of' is a link.
'cards' is the third definition.
(deck of cards)
(Other definitions for deck that I've seen before include "Set of cards" , "Ship's flooring; pack" , "fell to floor" , "Pack - embellish - ship's floor" , "Pack - part of record player" .)
