IPA: /ɒmˈnɪvərəsli/
KK: /ɑmˈnɪvərəsli/
In a way that involves eating both plants and animals.
The bear omnivorously foraged for berries and fish in the river.
Omnivorously → It is formed from "omni-" (meaning all) and "vorare" (meaning to devour or eat). The word describes the manner of eating all kinds of food, both plant and animal.
Think of 'all' ('omni-') being 'devoured' ('vorare') — that's why omnivorously means eating all types of food.
