Links some business up with the French (7)
I believe the answer is:
couples
'links' is the definition.
The definition and answer can be both quantities as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'business up with the french' is the wordplay.
'business' becomes 'co' (short for company).
'with' means one lot of letters go next to another.
'the french' becomes 'les' (plural form of 'the' in French).
'co'+'up'+'les'='COUPLES'
'some' is the link.
Can you help me to learn more?
(Other definitions for couples that I've seen before include "Pairs" , "People with their partners" .)
