NAACP co-founder Wells (3)
I believe the answer is:
ida
'naacp co-founder wells' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ida that I've seen before include "Mountain in Crete" , "Stagey princess" , "princess on stage" , "Classical mountain" , "The girl for Dai" .)
