IPA: /dɪsˈjuːnɪti/
KK: /dɪsˈjunɪti/
A state of not being united or joined together; a situation where there is disagreement or conflict among a group.
The disunity among the team members led to poor performance in the competition.
Disunity → It is formed from "dis-" (meaning apart) and "unity" (from Latin "unitas", meaning oneness or being one). The word "disunity" refers to a state of being apart or lacking unity.
Think of being 'apart' ('dis-') from 'oneness' ('unity') — that's why disunity means a lack of togetherness.
