Blaze almost gets tree (3)
I believe the answer is:
fir
'tree' is the definition.
(fir tree is a kind of tree)
'blaze almost' is the wordplay.
'blaze' becomes 'fire' (I've seen this in another clue).
'almost' means to remove the last letter (most of the word but not all of it).
'fire' with its final letter taken off is 'FIR'.
'gets' is the link.
(Other definitions for fir that I've seen before include "Pine tree for Gaelic men?" , "Tree for Irishmen" , "Evergreen conifer" , "Evergreen tree for Irish men?" , "Scots pine" .)
