Marines in a group of musicians displaying part of insignia? (7)
I believe the answer is:
armband
'part of insignia?' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'marines in a group of musicians' is the wordplay.
'marines' becomes 'RM' (abbreviation for 'Royal Marines').
'in' is an insertion indicator.
'group of musicians' becomes 'band' (I've seen this before).
'a'+'band'='aband'
'rm' inserted into 'aband' is 'ARMBAND'.
'displaying' acts as a link.
Can you help me to learn more?
(Other definitions for armband that I've seen before include "support for member" , "Ring for captain" , "Inflatable aid for those learning to swim" , "It signals captain" , "part of the uniform" .)
