Rickety vehicle, shake catch (10)
I believe the answer is:
rattletrap
'rickety vehicle' is the definition.
(I've seen this before)
'shake catch' is the wordplay.
I cannot quite see how this works, but
'shake' could be 'rattle' (rattling is a kind of shaking) and 'rattle' is found within the answer.
'catch' could be 'trap' (trapping is a kind of catching) and 'trap' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rattletrap that I've seen before include "Old car" , "banger" , "jalopy" , "Rickety vehicle" , "Vehicle, wobbly" .)
