Savages have key minerals (5)
I believe the answer is:
gores
'savages' is the definition.
Although both the answer and definition are verbs in their -s form, I can't understand how one could define the other.
'key minerals' is the wordplay.
'key' becomes 'g' (musical key).
'minerals' becomes 'ores' (ore is a kind of mineral).
'g'+'ores'='GORES'
'have' is the link.
Can you help me to learn more?
(Other definitions for gores that I've seen before include "Impales in beastly fashion" , "Pierces with horn like bull" .)
