I believe the answer is:

alexander

I'm a little stuck... Click here to teach me more about this clue!

'great man' is the definition.
(Alexander the Great)

I can't explain the rest of the clue.

(Other definitions for alexander that I've seen before include "The Great Man" , "who developed special technique?" , "Ancient king of Macedon" , "Boy" , "A Great king of old Macedon" .)

I've seen this clue in The Daily Express.
