Louder → It is formed from "loud" (from Old English *hlud*, meaning having a strong sound) and "-er" (a comparative suffix meaning more). The word "louder" means having a greater volume or intensity of sound than something else.
Think of 'loud' as having a strong sound, and the '-er' means more. So, louder means more strong sound.
