Trade second-class craft with hesitation (6)
I believe the answer is:
barter
'trade' is the definition.
('barter' can be a synonym of 'trade')
'second-class craft with hesitation' is the wordplay.
'second class' becomes 'b'.
'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 by exchanging commodities" , "Trade or swap" , "Give (goods) in exchange" , "Exchange goods without using money" , "Trade by direct exchange of goods" .)
