Cherished name in Calcutta (6)
I believe the answer is:
teresa
'cherished name in calcutta' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for teresa that I've seen before include "Saint" , "Mother...saintly nun of Calcutta" , "Mother of Calcutta, 1910-97" , "Girl's name" , "Mother . . . . . ., saintly nun of Calcutta" .)
