Whitney who invented the cotton gin (3)
I believe the answer is:
eli
'whitney who invented the cotton gin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eli that I've seen before include "Highest priest at Shiloh" , "High priest in the Book of Samuel" , "- Wallach, US actor" , "Distort then untruth to get a Biblical character" , "Man" .)
