Some horseshoes may be seen in the garden (3)
I believe the answer is:
hoe
'garden' is the definition.
(to garden could mean to hoe)
'some horseshoes may' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'HOE' can be found hidden inside 'horseshoes may'.
'be seen in the' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for hoe that I've seen before include "Gardening tool" , "Weeding tool" , "Weeding implement" , "Garden tool with a flat blade" , "Plymouth - -" .)
