IPA: /dɪsˈbændmənt/
KK: /dɪsˈbændmənt/
The action of ending or dissolving a group or organization.
The disbandment of the committee was announced after the project was completed.
Disbandment is formed from "dis-" (meaning apart) and "band" (from Old French *bander*, meaning to bind or tie). The suffix "-ment" (meaning the action or result of) indicates the process of breaking apart or dissolving a group that was previously bound together.
Think of 'dis-' meaning apart and 'band' referring to a group that was tied together. This helps you remember that 'disbandment' means the action of breaking a group apart.
