IPA: /ˌdɪsɪnˈhɛrɪtəns/
KK: /dɪsɪnˈhɛrɪtəns/
The action of taking away someone's right to inherit property or money from a family member, usually through a legal process.
The disinheritance of the eldest son caused a lot of family disputes.
Disinheritance → It is formed from "dis-" (meaning apart or away) and "inheritance" (from Latin "inhereditare", meaning to receive as an heir). The word describes the act of taking away someone's right to inherit, effectively separating them from their inheritance.
Think of being 'separated' ('dis-') from what you would normally 'receive as an heir' ('inheritance'). This helps you remember that disinheritance means losing the right to inherit.
