Gardener almost goes off on the warpath (7)
I believe the answer is:
enraged
'on the warpath' is the definition.
I can't judge whether this defines the answer.
'gardener almost goes off' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'goes off' is an anagram indicator.
'gardener' with its last letter removed is 'gardene'.
'gardene' with letters rearranged gives 'ENRAGED'.
Can you help me to learn more?
(Other definitions for enraged that I've seen before include "Made very angry" , "Wound up" , "with all guns blazing" , "upset" , "Incensed" .)
