Trendy couple entering outside area in coat (9)
I believe the answer is:
paintwork
'coat' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'trendy couple entering outside area' is the wordplay.
'trendy' becomes 'in' ('in' can mean fashionable).
'couple' becomes 'two' (two people or things).
'entering' indicates putting letters inside.
'outside area' becomes 'park' (park is a kind of area. I am not sure about the 'outside' bit.).
'in'+'two'='intwo'
'intwo' placed into 'park' is 'PAINTWORK'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for paintwork that I've seen before include "Coats maybe" , "matt and gloss?" , "Decoration" .)
