Rock collection to play in scene intermittently (5)
I believe the answer is:
cairn
'rock collection' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'play in scene intermittently' is the wordplay.
'play' becomes 'air' (I am not sure about this - if you are sure you should believe this answer much more).
'in' is an insertion indicator.
'intermittently' indicates alternate letters.
The alternate letters of 'scene' are 'cn'.
'air' going within 'cn' is 'CAIRN'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for cairn that I've seen before include "Agree" , "Burial mound" , "Heap of stones as a monument" , "Heap of stones - terrier" , "Mound of stones erected as marker" .)
