IPA: /ˈʌpˌɡroʊθ/
KK: /ˈʌpˌɡroʊθ/
The process of growing or developing in an upward direction.
The upgrowth of the plants was evident after the rain.
Upgrowth → It is formed from "up" (meaning in a higher position or direction) and "growth" (from Old English "growan", meaning to grow or increase). The word "upgrowth" refers to the process of growing or increasing in a higher direction or position.
Think of something moving 'up' and 'growing' — that's why upgrowth means an increase in height or elevation.
