Articulated lorry of American origin (3)
I believe the answer is:
rig
'articulated lorry' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'of american origin' is the wordplay.
'of' says the answer is hidden in the clue.
'RIG' can be found hidden inside 'american origin'.
Can you help me to learn more?
(Other definitions for rig that I've seen before include "Apparatus; fix" , "Masts, spars and sails on a vessel" , "Manipulate; (oil exploration) apparatus" , "Large American lorry" , "Manage or control fraudulently, say an election" .)
