Running away to sea (6)
I believe the answer is:
ebbing
This clue might be a double definition.
'running away' is the first definition.
The answer and definition can be both to do with motion as well as being present participle verbs.
Perhaps they are linked in a way I don't understand?
'sea' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for ebbing that I've seen before include "Gradually growing less" , "Receding like Big Ben" , "in decline?" , "Declining" , "Flowing out" .)
