Frenchman too much for rocker's enemy (3)
I believe the answer is:
mod
'rocker's enemy' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'frenchman too much' is the wordplay.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'too much' becomes 'od' (abbreviation for overdose).
'm'+'od'='MOD'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for mod that I've seen before include "Gaelic literary festival" , "Rocker's rival?" , "1960s teenager" , "Meeting of the Scottish" , "ministry" .)
