Usage
What does dissonant mean? Dissonant is an adjective used to describe noise that’s harsh and inharmonious. It’s also used to describe things that are in stark disagreement or that lack consistency. In both cases, a close synonym is discordant. The state of being dissonant is dissonance. In the context of music, dissonant is used to describe a combination of sounds thought to be inharmonious (often ones intentionally composed to be so). Such a combination (or a chord or interval that features such disharmony) is called dissonance. In psychology, the term cognitive dissonance refers to the unease a person feels when they have two or more contradictory or incompatible beliefs. Such thoughts can be described as dissonant. Example: Leaders in both factions of the party promised harmony, but so far there has been nothing but dissonant rhetoric.

Etymology
Origin of dissonant
1400–50; late Middle English dissonaunte (< Anglo-French ) < Latin dissonant- (stem of dissonāns, present participle of dissonāre to sound harsh), equivalent to disson- (derivative of dissonus discordant; see dis- 1, sound 1) + -ant- -ant
Explanation
If things don't go together well, you can call them dissonant. Dissonant voices are saying different things. Dissonant clothing choices clash. Dissonant chords lack harmony. The word dissonant comes from the Old French dis- meaning "apart" and sonare meaning "to sound." When a noise is dissonant, it sounds like it's broken apart, or not meshing together well. Dissonant doesn't have to describe just music or sounds. It can also refer to something that clashes or doesn't fit well together. When two people's versions of a story are dissonant, that means they don't match. Either one of them is lying or they just don't see eye-to-eye.
