Scathing report on lorry you loaned (9)
I believe the answer is:
truculent
'scathing' is the definition.
(thesaurus)
'report on lorry you loaned' is the wordplay.
I cannot quite see how this works, but
'you' could be 'u' (commonly used in online communication) and 'u' is found within the answer.
'loaned' could be 'lent' ('lend' can be a synonym of 'loan') and 'lent' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for truculent that I've seen before include "Rude and aggressive" , "Defiant, rude" , "Aggressively defiant" , "Defiantly aggressive" , "Obstreperous" .)
