The phrase "take to wife" refers to the act of marrying someone. It's a traditional term that can sound outdated in modern speech. If you are looking for synonyms to use instead, some options include "get married to," "wed," "tie the knot with," "exchange vows with," "become husband and wife," and "join in matrimony." These alternatives can help you express the same concept more naturally and conversationally. It's important to use language that fits the tone and context of your conversation or writing, whether you're discussing love, commitment, or simply making plans for the future.
