Urban resident to admit severing link (6)
I believe the answer is:
townie
'urban resident' is the definition.
'townie' can be an answer for 'resident' (townie is a kind of resident). I am not certain of the 'urban' bit.
'admit severing link' is the wordplay.
I cannot really understand how this works, but
'admit' could be 'own' (own can mean to admit or acknowledge) and 'own' is found within the answer.
'link' could be 'tie' (synonyms) and 'tie' is found in the leftover letters.
No letters remain.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for townie that I've seen before include "city type" , "knows little of the country?" , "Inhabitant of an urban area" , "citizen" , "Non-country dweller" .)
