Highland photographer not working in Iona (9)
I believe the answer is:
snowdonia
'highland' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?
'photographer not working in iona' is the wordplay.
'photographer' becomes 'snowdon' (I am not sure about this - if you are sure you should believe this answer much more).
'not' is a deletion indicator.
'working in' becomes 'on' (I've seen this in other clues).
'iona' with 'on' taken out is 'ia'.
'snowdon'+'ia'='SNOWDONIA'
Can you help me to learn more?
(Other definitions for snowdonia that I've seen before include "massif region" , "National park in Wales" , "Welsh mountain region" , "peaks" , "Win a snood in the Welsh county" .)
