In a way that involves different kinds or types; not uniform or consistent.
The students were grouped heterogeneously to encourage diverse interactions.
Heterogeneously → It is formed from "hetero-" (from Greek "heteros", meaning different) and "genus" (from Latin, meaning kind or type) and the suffix "-ly" (meaning in a manner). The word describes something that is characterized by being of different kinds or types.
Think of 'different' ('hetero-') kinds or types ('genus') and how they are mixed together — that's what heterogeneously means.
