Awkward finding clutter in front of garage (9)
I believe the answer is:
lumbering
'awkward' is the definition.
(to lumber is to move awkwardly)
'clutter in front of garage' is the wordplay.
I cannot really understand how this works, but
'in' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'finding' is the link.
Can you help me to learn more?
(Other definitions for lumbering that I've seen before include "Moving in heavy clumsy way" , "Awkward" , "Ponderous" .)
