Significant other (SO) is colloquially used as a gender-blind term for a person’s partner in an intimate relationship without disclosing or presuming anything about marital status, relationship status, or sexual orientation, as it is vague enough to avoid offense by using a term that an individual might consider inappropriate (e.g. lover when he or she considers him a boyfriend, or girlfriend sweetheart, love, lover, when he considers her a soul-mate, or life partner).
