Trade British craft with hesitation (6)
I believe the answer is:
barter
'trade' is the definition.
('barter' can be a synonym of 'trade')
'british craft with hesitation' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'craft' becomes 'art' (I've seen this before**).
'with hesitation' becomes 'er' (I've seen this in other clues).
'b'+'art'+'er'='BARTER'
(Other definitions for barter that I've seen before include "Trade, haggle" , "Trade not involving money" , "Trade without using money" , "Trade by direct exchange of goods" , "Exchange goods without using money" .)
