The word 'letterman' is formed from 'letter' (from Old French *lettre*, meaning a written character or symbol) and 'man' (from Old English *mann*, meaning a person). A letterman is a person associated with letters, often referring to someone who has earned a letter in a sport or academic achievement.
Think of a 'letter' as a written character and 'man' as a person — a letterman is someone recognized for their achievements in letters or sports.
