Series of scores, ultimately? (6)
I believe the answer is:
result
'series' 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 don't see?
'of scores ultimately?' is the wordplay.
'of' says the answer is hidden in the clue.
'RESULT' can be found hidden inside 'scores ultimately'.
Can you help me to learn more?
(Other definitions for result that I've seen before include "Effect of lustre" , "Outcome of an undertaking" , "Verdict" , "Consequence in Ulster (6)" , "Final outcome" .)
