Covered dock in Alabama with store and staff (10)
I believe the answer is:
alpenstock
'staff' is the definition.
(alpenstock is a kind of staff)
'covered dock in alabama with store' is the wordplay.
I cannot really see how this works, but
'dock' could be 'pen' (I've seen this in other clues) and 'pen' is found in the answer.
'alabama' could be 'al' (abbreviation) and 'al' is located in the answer.
'store' could be 'stock' (synonyms) and 'stock' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for alpenstock that I've seen before include "Mountain climber's staff with a metal point" , "Metal-tipped mountaineering stick" , "climbing equipment" , "Stick with a metal point, used by hillwalkers" .)
