Chanted word (6)
I believe the answer is:
mantra
'chanted word' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mantra that I've seen before include "it's said to aid concentration" , "Word or phrase repeated as aid to concentration" , "Incantation used as aid to meditation" , "Sacred text used as incantation" , "Buddhist aid to concentration" .)
