IPA: /ˈɡɪltiər/
KK: /ˈɡɪltiər/
Feeling or showing a sense of responsibility for a wrongdoing or a mistake, especially when compared to someone else.
After forgetting her friend's birthday, she felt guiltier than ever.
Comparative: guiltier
Superlative: guiltiest
Guiltier → It is formed from "guilt" (from Old English "gylt", meaning a crime or sin) and the comparative suffix "-ier" (meaning more). The word "guiltier" means more guilty or having a greater sense of guilt than another.
Think of 'guilt' as a feeling of having done something wrong, and the '-ier' indicates a comparison, so 'guiltier' means having more guilt.
