IPA: /ˈhʌŋɡəri/
KK: /hʌŋɡri/
Feeling a stronger desire for food than usual.
After skipping breakfast, I felt hungrier than ever by lunchtime.
Hungrier → The word is formed from "hungry" (from Old English "hungrig", meaning having a strong desire for food) and the comparative suffix "-er" (meaning more). Thus, "hungrier" means having a greater desire for food than usual.
Think of someone who is 'more' ('-er') 'desiring food' ('hungry') — that's why hungrier means having a greater desire for food.
