Compel using spoken Gaelic when having company over (6)
I believe the answer is:
coerce
'compel' is the definition.
(coercing is a kind of compelling)
'spoken gaelic when having company over' is the wordplay.
I cannot really see how this works, but
'company' could be 'co' (abbreviation) and 'co' is found within the answer.
This explanation may well be incorrect...
'using' acts as a link.
Can you help me to learn more?
(Other definitions for coerce that I've seen before include "Force (someone) to do something" , "Oblige by force" , "Make or compel" , "Force, pressure" , "Persuade (the unwilling) by force" .)
