IPA: /ˈpeɪlər/
KK: /ˈpeɪlər/
Having less color or brightness than something else; lighter in shade.
The sky was paler than usual after the storm.
Paler → It is formed from "pale" (from Old French *pâle*, meaning lacking color or brightness) and "-er" (meaning one who or that which). The word "paler" describes something that is more lacking in color or brightness compared to something else.
Think of something that is 'lacking color' ('pale') and remember that 'paler' means more so — it's like saying more lacking in brightness.
