Tool gets learner out of difficulty (3)
I believe the answer is:
hoe
'tool' is the definition.
(hoe is a kind of tool)
'learner out of difficulty' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'out of' indicates named letters should be taken away ('out of' can mean no longer having).
'difficulty' becomes 'hole' (hole can mean a difficult situation).
'hole' with 'l' taken out is 'HOE'.
'gets' is the link.
(Other definitions for hoe that I've seen before include "Attend to beds" , "Weed" , "Weeding implement" , "Garden tool with a flat blade" , "Use garden tool" .)
