It could be relevant for awkward painter (7)
I believe the answer is:
pertain
'it could be relevant' is the definition.
The definition suggests a singular noun but the answer is not.
'awkward painter' is the wordplay.
'awkward' is an anagram indicator.
'painter' anagrammed gives 'PERTAIN'.
'for' is the link.
Can you help me to learn more?
(Other definitions for pertain that I've seen before include "Be relevant, or belong as part" , "Be related or applicable (to something)" , "Refer" , "Have relevance" , "Relate (to), apply (to)" .)
