IPA: /ˈskɪniər/
KK: /ˈskɪniər/
Having less body fat or being thinner than someone or something else.
After months of exercise, she became skinnier than before.
Skinnier → It is formed from "skin" (from Old Norse *skinn*, meaning the outer covering of an animal) and the comparative suffix "-ier" (meaning more). The word "skinnier" means having less flesh or being more thin than something else.
Think of the word 'skin' as the outer covering, and when something is 'skinnier', it means it has less flesh or is more thin than before.
