Prime team? (6)
I believe the answer is:
eleven
This clue might be a double definition.
'prime' is the first definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe there's a link between them I don't understand?
'team?' is the second definition.
(eleven is a kind of team)
Can you help me to learn more?
(Other definitions for eleven that I've seen before include "Time for morning coffee" , "Cardinal" , "Lowest two-digit prime" , "XI as Roman numeral" , "sports team?" .)
