Travel around end of garden? One might (5)
I believe the answer is:
snail
'one might' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'travel around end of garden?' is the wordplay.
'travel' becomes 'sail' (sail is a kind of travel**).
'around' indicates putting letters inside.
'end of' indicates one should take the final letters.
The final letter of 'garden' is 'n'.
'sail' going around 'n' is 'SNAIL'.
(Other definitions for snail that I've seen before include "Slow mover" , "French delicacy" , "Edible terrestrial mollusc" , "Slow slithery animal" , "dawdler" .)
