Circle pub argument — something to be carried on outside? (11)
I believe the answer is:
wheelbarrow
'something to be carried on outside?' is the definition.
(a wheelbarrow is used outside)
'circle pub argument' is the wordplay.
'circle' becomes 'wheel' (wheel can mean to circle or turn).
'pub' becomes 'bar' (both are drinking establishments).
'argument' becomes 'row' (to row is to argue).
'wheel'+'bar'+'row'='WHEELBARROW'
(Other definitions for wheelbarrow that I've seen before include "Gardening equipment" , "will carry weight" , "Garden cart" , "Garden carrier" , "Type of handcart" .)
