Perplexed to find none on shore? (3,2,3)
I believe the answer is:
all at sea
'find none on shore?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'perplexed' is the wordplay.
I cannot quite understand how this works, but
'perplexed' could be 'atsea' (similar in meaning) and 'atsea' is located in the answer.
The remaining letters 'all' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for all at sea that I've seen before include "in a muddle" , "Completely confused on voyage?" , "Entire crew" , "Rescuers at Dunkirk were thus" , "Situation with no sailors in port" .)
