Dirty article seen by relative (7)
I believe the answer is:
unclean
'dirty' is the definition.
(associated in meaning)
'article seen by relative' is the wordplay.
'article' becomes 'an' (indefinite article).
'seen by' is a charade indicator (letters next to each other).
'relative' becomes 'uncle' (uncle is a kind of relative).
'an' put after 'uncle' is 'UNCLEAN'.
(Other definitions for unclean that I've seen before include "Ceremonially impure" , "Spotted" , "Defiled" , "Dirty, ritually impure" , "Contaminated" .)
