Lorry driver and friar crossing river with hesitation (7)
I believe the answer is:
trucker
'lorry driver' is the definition.
(I've seen this before)
'friar crossing river with hesitation' is the wordplay.
'friar' becomes 'tuck' (Friar Tuck).
'crossing' indicates putting letters inside (to cross can mean to go over or around).
'river' becomes 'r' (abbreviation).
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'tuck' placed around 'r' is 'truck'.
'truck'+'er'='TRUCKER'
'and' acts as a link.
(Other definitions for trucker that I've seen before include "(US) lorry driver" , "One who has dealings with" , "I convey" , "Professional driver" , "Long-distance lorry driver" .)
