Interesting topic, addressing location (7,5)
I believe the answer is:
talking point
'interesting topic' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'addressing location' is the wordplay.
I cannot quite understand how this works, but
'location' could be 'point' (point is a kind of location) and 'point' is located in the answer.
The remaining letters 'talking' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for talking point that I've seen before include "matter for debate" , "Topic inviting discussion" , "Subject for discussion" , "Matter of discussion" .)
