Some boats, eastbound away from the land (2,3)
I believe the answer is:
at sea
'land' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I don't see?
'some boats eastbound away' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'AT SEA' can be found hidden inside 'boats eastbound away'.
'from the' acts as a link.
Can you help me to learn more?
(Other definitions for at sea that I've seen before include "Voyaging" , "Disorganised; bewildered" , "Perplexed" , "Where a packet might be" , "stumped" .)
