Heavyweight boxes with Barry? (4)
I believe the answer is:
town
'heavyweight boxes with barry?' is the definition.
I can't judge whether this defines the answer.
'heavyweight boxes with' is the wordplay.
'heavyweight' becomes 'ton' (a ton weighs a lot).
'boxes' is an insertion indicator (the outside letters must 'box' inside letters in).
'with' becomes 'w' (abbreviation).
'ton' enclosing 'w' is 'TOWN'.
Can you help me to learn more?
(Other definitions for town that I've seen before include "Urban area larger than a village" , "Nelson, for example" , "Borough" , "Built-up area" , "It lies between village and city" .)
