What Does Significant Other Mean?

In many social or business situations, the term 'significant other' refers to someone that offers support to another person as a friend, family member, partner or spouse. "SO" does not refer to gender or specific romantic entanglements, and does not specify the nature of the relationship. For instance, many hospitals now use 'significant other' in their paperwork to refer to a person who can offer support during testing, treatment or illness.

Many companies will use significant other on their invitations or announcements to share that the people attending the event can bring a plus one.

In the dating world, a significant other refers to a partner, girlfriend, boyfriend, spouse or someone with whom we share an intimate, romantic relationship with. Because the term doesn't imply gender, sexuality or relationship status, many couples adopted the phrase in the 80s and 90s to avoid offense or confusion.

As an example, say you were chatting with a friend online about an upcoming wedding and you wanted to know if you could bring someone with you. Many people would ask, "Can I bring a significant other?" and then the conversation would continue. By saying significant other, the person asking isn't saying girlfriend when they really mean an "um... friend", or lover when they really want to say friends with benefits. No one gets the wrong idea when you say significant other, and nobody's feelings get hurt.

Where The Term Significant Other Came From

The term significant other originated in 1953 with a US-based psychiatrist by the name of Harry Stack Sullivan, where he published it in a book called, "The Interpersonal Theory of Psychiatry".
