Comparative: older
Superlative: oldest
Older → It is formed from "old" (from Old English *eald*, meaning having lived for a long time) and the comparative suffix "-er" (meaning more). The word "older" means having more age or being greater in age than something or someone else.
Think of 'old' as having lived a long time, and the '-er' indicates more of that quality — so older means more old.
