Weakening digital connection cuts off West (6)
I believe the answer is:
ebbing
'west' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'weakening digital connection cuts' is the wordplay.
'weakening' becomes 'ebb' (I've seen this in another clue).
'digital connection cuts' becomes 'ing' (I can't explain this - if you can you should give a lot more credence to this answer).
'ebb'+'ing'='EBBING'
'off' acts as a link.
Can you help me to learn more?
(Other definitions for ebbing that I've seen before include "Flowing out" , "Declining" , "Going out like a tide" , "in decline?" , "Receding like Big Ben" .)
