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' indicates the answer is hidden within the clue.
'ASANA' is hidden in the letters of 'was anagrammed'.
(Other definitions for asana that I've seen before include "Yoga position" , "Yoga posture" , "Spiritual position" , "meditative posture" .)
