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 quite understand how this works, but
'dock' could be 'pen' (I've seen this in other clues) and 'pen' is found within the answer.
'alabama' could be 'al' (abbreviation) and 'al' is present in the answer.
'store' could be 'stock' (synonyms) and 'stock' is found in the answer.
This accounts for all the letters.
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" .)
