IPA: /ˈhænsəmər/

More attractive or good-looking than someone or something else.
He is handsomer than his brother.
Handsomer → It is formed from "hand" (from Old English "hand", meaning the end part of a person's arm) and "-some" (meaning characterized by or having a specified quality). The word "handsomer" means characterized by having a pleasing appearance, particularly in reference to a man's looks, suggesting a quality of being handsome.
Think of 'hand' as the part of the body that can be pleasing to see, and '-some' means having that quality. This helps you remember that 'handsomer' refers to someone who is more pleasing in appearance.
