Charmingly displaying branch (3)
I believe the answer is:
arm
'branch' is the definition.
(thesaurus)
'charmingly displaying' is the wordplay.
'displaying' indicates a hidden word.
'ARM' can be found hidden inside 'charmingly'.
(Other definitions for arm that I've seen before include "Equip with a limb" , "Activate fuse" , "Test of strength with elbows on the table" , "Human limb" , "Maybe rifle" .)
