What does SO mean?

Significant other

If you’re in a romantic relationship, you might use the term SO to refer to your partner. This acronym stands for “significant other,” which is another way to say boyfriend, girlfriend, husband, wife, or any other type of romantic partner.

The beauty of the term SO is that it’s gender-neutral. So, it’s a great option if you want to talk about your partner without specifying their gender or the nature of your relationship.

People often use SO when they’re chatting about their love life. Maybe they like this term more than the traditional ones, or perhaps they don’t want to label their relationship yet. Either way, it’s a handy acronym to know.
