W.N.B.A. great Weatherspoon (6)

I believe the answer is:

teresa

(Other definitions for teresa that I've seen before include "Girl's name" , "Mother ..., who ministered to the poor in India" , "Woman" , "Mother of Calcutta, 1910-97" , "Nun who was dedicated to helping the poor of Calcutta" .)

I've seen this clue in The New York Times.
