It grows in entree (4)
I believe the answer is:
tree
'it grows' is the definition.
'entree' is the wordplay.
'TREE' is hidden within the letters.
But, I am uncertain how the hidden word is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for tree that I've seen before include "Be up a .... to be in difficulties" , "Recently named grouping of rogue states" , "Oak, for example" , "Plane possibly" , "Eg, laburnum" .)
