Terribly nice mum in fleapit (6)
I believe the answer is:
cinema
'fleapit' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'terribly nice mum' is the wordplay.
'terribly' is an anagram indicator.
'mum' becomes 'ma' (ma can mean mother).
'nice' is an anagram of 'cine'.
'cine'+'ma'='CINEMA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cinema that I've seen before include "The flicks" , "Movie house" , "Modern art" , "Movie theatre" , "place for pictures" .)
