/ɪn lɔː ˈrɛlətɪv/ – Phrase
Definition: người thông gia, người sui gia.
A more thorough explanation: In legal terms, the word “in-law” refers to a person who is related to another person by marriage, rather than by blood. For example, a mother-in-law is the mother of one’s spouse, and a brother-in-law is the brother of one’s spouse.
Example: My sister-in-law is coming to visit us next weekend.
