Tool for weeding (3)
I believe the answer is:
hoe
'tool for weeding' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hoe that I've seen before include "Purple gem" , "Romanians (anag) -- European enclave" , "Tool for loosening soil and scraping up weeds" , "Garden tool for scraping up weeds" , "gardening implement" .)
