Levirate marriage

Wikipedia's first sentence called it “practice of a woman marrying one of her husband 's sons or brothers after her husband's death”. Today it says “type of marriage in which the brother of a deceased man is obliged to marry his widowed sister-in-law”. The one-line description Wikipedia serves to search engines and AI systems read “Type of marriage”. It now reads “Obligatory marriage between a widow and a brother of the deceased”.
