Europium and vanadium in mineral? A lot of work here (6)
I believe the answer is:
oeuvre
'a lot of work here' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'europium and vanadium in mineral?' is the wordplay.
'europium' becomes 'Eu' (Eu is the chemical symbol for europium).
'and' is a charade indicator (letters next to each other).
'vanadium' becomes 'V' (chemical symbol).
'in' is an insertion indicator.
'mineral?' becomes 'ore' (ore is a kind of mineral).
'eu'+'v'='euv'
'euv' placed inside 'ore' is 'OEUVRE'.
Can you help me to learn more?
(Other definitions for oeuvre that I've seen before include "Artist's total output" , "Substantial body of work from our Eve" , "Complete output of a writer or artist" , "All one's writings" , "Complete works (Fr.)" .)
