Hens fluttering around me, get mixed up (6)
I believe the answer is:
enmesh
'get mixed up' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how they can define each other.
'hens fluttering around me' is the wordplay.
'fluttering' indicates anagramming the letters.
'around' is an insertion indicator.
'hens' with letters rearranged gives 'ensh'.
'ensh' enclosing 'me' is 'ENMESH'.
Can you help me to learn more?
(Other definitions for enmesh that I've seen before include "Men she changed to entangle" , "Entrap" , "Entangle as in net" , "Make tangled as if in a net" , "Tangle up in a net" .)
