Look for a feature about double-parking (6)
I believe the answer is:
appear
'look' is the definition.
(synonyms)
'feature about double-parking' is the wordplay.
'feature' becomes 'ear' (ears are a facial feature).
'about' means one lot of letters go next to another.
'double parking' becomes 'app' (I can't justify this - if you can you should give a lot more credence to this answer).
'ear' put after 'app' is 'APPEAR'.
'for a' is the link.
Can you help me to learn more?
(Other definitions for appear that I've seen before include "be published" , "Present oneself" , "Arrive" , "Come into sight, materialise" , "become available" .)
