Service to leave bird of peace, accepted as digger’s reward? (4)
I believe the answer is:
vein
'digger's reward?' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'service to leave bird of peace accepted' is the wordplay.
I cannot quite see how this works, but
'accepted' could be 'in' (I've seen this in other clues) and 'in' is present in the answer.
This explanation may well be incorrect...
'as' acts as a link.
Can you help me to learn more?
(Other definitions for vein that I've seen before include "Speaker's useless" , "Distinctive quality" , "Rock fissure or minerals therein" , "Seam of mineral" , "Leaf rib; ore layer in rock" .)
