Yoga pose was anagrammed, partially (5)
I believe the answer is:
asana
'yoga pose' is the definition.
(I've seen this in another clue)
'was anagrammed partially' is the wordplay.
'partially' says the answer is hidden in the clue.
'ASANA' can be found hidden inside 'was anagrammed'.
(Other definitions for asana that I've seen before include "Yoga position" , "Yoga posture" , "Spiritual position" , "meditative posture" .)
