The team emerges one by one (6)
I believe the answer is:
eleven
'the team' is the definition.
(eleven is a kind of team)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for eleven that I've seen before include "Number, on a team maybe" , "Cricketing side" , "Time for the mid-morning tea break?" , "football team, for example" , "Prime number" .)
