IPA: /ɪnˈkɒŋɡruəntli/
KK: /ɪnˈkɒŋɡruəntli/
In a way that does not match or is not in harmony with something else.
The colors in the painting were used incongruently, making it hard to focus on the main subject.
Incongruently → It is formed from "in-" (meaning not) and "congruere" (meaning to agree or fit together) and the suffix "-ly" (meaning in a manner). The word describes something that does not fit together or is not in agreement in a particular manner.
Think of 'not' fitting together ('in-') and 'agreeing' ('congruere') — that's why incongruently means something that does not fit or agree in a certain way.
