Unionist made out an upward path? (12)
I believe the answer is:
mountainside
'an upward path?' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'unionist made out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'unionist'+'made'='unionistmade'
'unionistmade' is an anagram of 'MOUNTAINSIDE'.
Can you help me to learn more?
(Other definitions for mountainside that I've seen before include "where many adventurous explorers go?" , "It isn't flat" , "One's inclined" , "Incline" , "Big hill slope" .)
