Question notice by second team (5)
I believe the answer is:
squad
'team' is the definition.
('squad' can be a synonym of 'team')
'question notice by second' is the wordplay.
'question' becomes 'qu'.
'notice' becomes 'ad'.
'by' says to put letters next to each other.
'second' becomes 's' (common abbreviation).
'qu'+'ad'='quad'
'quad' put after 's' is 'SQUAD'.
(Other definitions for squad that I've seen before include "Smallest army unit" , "Small group of soldiers or police" , "Body of soldiers" , "Group (of soldiers, players etc)" , "Pool of players" .)
