Disinherit → It is formed from "dis-" (meaning apart or away) and "inherit" (from Latin "hereditare", meaning to receive or inherit). The word describes the act of taking away someone's right to receive an inheritance, effectively separating them from it.
Think of being 'separated' ('dis-') from what you would normally 'receive' ('inherit') — that's why disinherit means to take away someone's right to inherit.
