IPA: /dɪsˈpreɪzɪŋli/
KK: /dɪsˈpreɪzɪŋli/
In a manner that expresses disapproval or criticism.
She spoke dispraisingly about the new policy at the meeting.
Dispraisingly → It is formed from "dis-" (meaning apart or away) and "praise" (from Old French *priser*, meaning to value or esteem) and the suffix "-ingly" (meaning in a manner). The word describes the manner of speaking or acting in a way that diminishes or takes away from praise.
Think of 'dis-' meaning to take away and 'praise' meaning to value — so when something is done 'dispraisingly', it means it takes away from the value or esteem.
