The English language has a rich vocabulary, and there are many different words and phrases that can be used to refer to one's spouse. Some of these terms are more formal, while others are more informal or affectionate.
Here is a list of some of the most common words and phrases for spouse:
Love of my life
Old lady/old man
Some of these terms are more commonly used in certain contexts than others. For example, "husband" and "wife" are typically used in formal settings, such as in legal documents or wedding invitations. "Spouse" is a more general term that can be used in any context. "Partner" and "significant other" are often used by people who are not legally married, but who are still in a committed relationship.
The terms "other half" and "better half" are both terms of endearment that suggest that the speaker and their spouse are two halves of a whole. "Dear one," "beloved," "love of my life," and "soulmate" are all affectionate terms that express the speaker's deep love and affection for their spouse.
The terms "life partner" and "old ball and chain" are both more lighthearted terms that can be used to refer to one's spouse in a casual setting. "Hubby" and "wifey" are also informal terms that are often used between spouses.
The terms "bae" and "boo" are more recent terms that have become popular in recent years. They are often used by younger people and are considered to be terms of affection.
Which term you choose to use to refer to your spouse will depend on your personal preference and the context in which you are using it. If you are unsure which term to use, it is always best to err on the side of caution and use a more formal term.
