IPA: /dɪsˈɒnərəbli/
KK: /dɪsˈɒnərəbli/
In a way that brings shame or disgrace.
He acted dishonorably by betraying his friends.
Dishonorably → It is formed from "dis-" (meaning apart or away) and "honor" (from Latin "honor", meaning respect or esteem) and the suffix "-ably" (meaning in a manner). The word "dishonorably" means in a manner that is away from or lacking respect or esteem.
Think of 'dis-' meaning apart and 'honor' meaning respect — so when someone acts dishonorably, they are acting in a way that is apart from respect.
