Lip from Trimurti (3)
I believe the answer is:
rim
'lip' is the definition.
(I know that lip can be written as rim)
'from trimurti' is the wordplay.
'from' says the answer is hidden in the clue.
'RIM' can be found hidden inside 'trimurti'.
(Other definitions for rim that I've seen before include "An edge, canyon or cup" , "Edge or margin" , "Edge, border" , "Flange" , "Upper or outer edge" .)
