IPA: /dɪsˈoʊnmənt/
KK: /dɪsˈoʊnmənt/
The act of refusing to acknowledge or maintain a relationship with someone, often a family member.
After the argument, he faced the painful disownment by his parents.
Disownment → It is formed from "dis-" (meaning apart or away) and "own" (from Old English "agan", meaning to possess or have). The suffix "-ment" (meaning the action or result of) indicates the process of no longer possessing or acknowledging something. Thus, disownment refers to the act of no longer acknowledging or claiming someone as one's own.
Think of 'dis-' meaning 'apart' and 'own' meaning 'to possess' — disownment is the act of separating oneself from possession or acknowledgment.
