Tool kept in shoes (3)
I believe the answer is:
hoe
'tool kept in shoes' is the definition.
'hoe' can be an answer for 'tool' (thesaurus). I'm unsure of the 'kept in shoes' bit.
'in shoes' is the wordplay.
'in' indicates the answer is hidden within the clue.
'HOE' is hidden in the letters of 'shoes'.
Can you help me to learn more?
(Other definitions for hoe that I've seen before include "Tool for loosening soil and scraping up weeds" , "Tool; promontory" , "Weeder" , "Use garden tool" , "Weed" .)
