Victory in Sidmouth for vital suppliers (5)
I believe the answer is:
veins
'vital suppliers' is the definition.
Although both the answer and definition are plural nouns, I can't understand how they can define each other.
'victory in sidmouth' is the wordplay.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'sidmouth' becomes 's' (this could be a standard abbreviation I've not previously seen).
've'+'in'+'s'='VEINS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for veins that I've seen before include "Layers of ore" , "Blood vessels" , "Circulation aids" , "Characteristic styles" .)
