Misinterprets alpine constituents' somewhat retro way of decorating walls (7)
I believe the answer is:
plaster
'way of decorating walls' is the definition.
I can't judge whether this defines the answer.
'misinterprets alpine constituents' somewhat retro' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'retro' says the letters should be written in reverse (retro is Latin for 'backwards').
'retsalp' is hidden in the letters of 'misinterprets alpine constituents'.
'retsalp' in reverse letter order is 'PLASTER'.
Can you help me to learn more?
(Other definitions for plaster that I've seen before include "Wall surface" , "Cover for cut" , "Small wound covering" , "Wall finish - protection for cut" , "Adhesive material" .)
