Murmured comments as the team comes in (6)
I believe the answer is:
asides
'murmured comments as the team comes in' is the definition.
I can't judge whether this defines the answer.
'as the team comes in' is the wordplay.
'the team' becomes 'side' (both can mean a sports team).
'comes in' means one lot of letters goes inside another.
'as' placed around 'side' is 'ASIDES'.
Can you help me to learn more?
(Other definitions for asides that I've seen before include "Incidental remarks" , "Remarks not for overhearing" , "communications not intended for everyone" , "Words spoken from corner of mouth" , "They're not heard by everybody" .)
