Honorific for Gandhi (7)
I believe the answer is:
mahatma
'honorific for gandhi' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mahatma that I've seen before include "Wise fellow" , "Holy man" , "(Indian) holy person or sage" , "Brahman sage" , "Asian holy person or sage." .)
