Difference between Spouse and Partner

From diff.wiki
Relationships are very important for human beings.

An acquaintance may come up to you and introduce someone as their partner, and this word may lead to some confusion. Do they mean a business partner? A close friend? Or their life partner? “Partner” is oftentimes used synonymously with “spouse”, but the two can be fundamentally different in some ways.

Spouse is generally used to refer to an individual that one is wed to, and has a legal implication on marriage. Spouse can be used interchangeably with “husband” or “wife”. A pair that identify with each other as a spouse can avail different benefits for married people such as filing a joint tax return or adding the other to a health insurance plan.

On the other hand, the term partner has a broader range of meaning. It can mean a business partner, a close associate, or anyone who associates with someone in a common interest. In the context of life partnership, the word can be used by people who are not legally wed. It can also be used to refer to a person involved in a domestic partnership, rather than a marriage. The word can also used in lieu of “husband” or “wife”, or the other half of a homosexual relationship.

A spouse can be called a partner, but a partner cannot be automatically referred to as one’s spouse.
