Crack by stupid European about English victory (8)
I believe the answer is:
crevasse
'crack' is the definition.
(crevasse is a kind of crack)
'stupid european about english victory' is the wordplay.
'stupid' becomes 'crass' (I've seen this before).
'european' becomes 'e' (abbreviation e.g. EU).
'about' is an insertion indicator.
'english' becomes 'e' (abbreviation).
'victory' becomes 'v'.
'crass'+'e'='crasse'
'e'+'v'='ev'
'crasse' going around 'ev' is 'CREVASSE'.
'by' is the link.
(Other definitions for crevasse that I've seen before include "big split" , "cold break" , "Deep glacial fissure" , "Sever sac (anag)" , "Deep glacial crack" .)
