Clothes appear to be tangled on line (7)
I believe the answer is:
apparel
'clothes' is the definition.
('apparel' can be a synonym of 'clothes')
'appear to be tangled on line' is the wordplay.
'to be tangled' indicates anagramming the letters.
'on' says to put letters next to each other.
'line' becomes 'l'.
'appear' is an anagram of 'appare'.
'appare'+'l'='APPAREL'
(Other definitions for apparel that I've seen before include "Fancy gear" , "Garb, clothes" , "Attire" , "Raiment" , "Pod of peas" .)
