Spouse is the marriage partner of a person.
The term spouse essentially means both husband and wife. The basic definition of “spouse” is someone you are married to.
The term is gender neutral and hence can be used to refer to either one. The phrase can be differentiated as the male spouse, which would refer to the husband, and the female spouse, which would refer to the wife.
However, the term is not only applicable in a traditional marriage. As marriage has various connotations today, so does the term spouse. “Spouse” can be used to describe a partner in a marriage, civil union, domestic partnership or common-law marriage.
