Lovely to see doctor since catching cold (6)
I believe the answer is:
scenic
'lovely' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'doctor since catching cold' is the wordplay.
'doctor' is an anagram indicator.
'catching' indicates putting letters inside.
'cold' becomes 'C' (eg on taps).
'since' anagrammed gives 'senic'.
'senic' enclosing 'c' is 'SCENIC'.
'to see' is the link.
Can you help me to learn more?
(Other definitions for scenic that I've seen before include "Like an attractive view" , "having a striking view" , "This route has pleasing vistas" , "Like beautiful location" , "Offering landscape views" .)
