Would you credit a sailor catching one in a boat? (4)
I believe the answer is:
crab
'one in a boat?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'would you credit a sailor' is the wordplay.
I cannot quite understand how this works, but
'credit' could be 'cr' and 'cr' is found within the answer.
'a' is within the answer.
A single letter 'b' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'catching' is the link.
Can you help me to learn more?
(Other definitions for crab that I've seen before include "Clawed crustacean" , "Edible crustacean" , "Fiddler, perhaps" , "accidentally caught in a row?" , "Clawed shellfish" .)
