Tree some vandal deracinated (5)
I believe the answer is:
alder
'tree' is the definition.
(I know that alder is a type of tree)
'some vandal deracinated' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ALDER' can be found hidden inside 'vandal deracinated'.
(Other definitions for alder that I've seen before include "Type of birch tree" , "Tree whose bark is used in tanning" , "Tree or shrub of the birch family" , "Tree growing in damp ground" , "Native tree" .)
