Programming pioneer Lovelace (3)
I believe the answer is:
ada
'programming pioneer lovelace' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ada that I've seen before include "girl?" , "Novel by Vladimir Nabokov" , "Palindromic girl's name" , "Computer lang.; f. name" , "- Lovelace, Byron's daughter & computer pioneer" .)
