Lied, “Suit is folded and used” (8)
I believe the answer is:
utilised
'used' is the definition.
('utilise' can be a synonym of 'use')
'lied suit is folded' is the wordplay.
'is folded' indicates an anagram.
'lied'+'suit'='liedsuit'
'liedsuit' is an anagram of 'UTILISED'.
'and' acts as a link.
(Other definitions for utilised that I've seen before include "Put to use" , "Suit idle? (anag)" , "Made practical use of" , "Used" , "Employed -- I led suit (anag)" .)
