IPA: /kənˈɡruːəsli/
KK: /kənˈɡruːəsli/
In a way that is suitable, appropriate, or harmonious with something else.
The colors in the painting were arranged congruously, creating a pleasing effect.
Congruously → It is formed from "con-" (meaning together) and "gruere" (from Latin, meaning to agree or fit). The suffix "-ously" indicates a manner or quality. Thus, "congruously" means in a manner that agrees or fits together harmoniously.
Think of things that fit or agree 'together' ('con-') — that's why when something happens congruously, it means it fits well together.
