Repeated word or phrase (6)
I believe the answer is:
mantra
This clue is a double definition.
'repeated word' is the first definition.
(I've seen this in another clue)
'phrase' is the second definition.
(I have seen 'Chanted phrase ' mean 'mantra' so perhaps 'phrase' could also mean 'mantra')
(Other definitions for mantra that I've seen before include "repeating phrase" , "Vedic hymn; slogan frequently repeated" , "Watchword" , "Incantation used as aid to meditation" , "Aid to concentration (Buddhism,Hinduism)" .)
