For years transgender activists have been fighting for visibility, including a push to distinguish cisgender as its own gender identity, rather than a socially accepted norm.

The Oxford English Dictionary has just added the word cisgender, which it defines as "designating a person whose sense of personal identity corresponds to the sex and gender assigned to him or her at birth."

The prefix "cis-" comes from Latin, and means "on this side of," whereas "trans-" indicates "across." With the entrance of the word into contemporary mainstream dialogue, its addition into the OED along with 500 new terms marks a huge step in opening up discourse about gender politics.

The term has gained a neutral popularity in the last 20 years, according to James Morton, transgender alliance manager at the Equality Network charity. He says, “Its addition to the Oxford English Dictionary reflects the significant increase in discussion of gender diversity over recent years. We welcome the increased awareness of its meaning which this inclusion will bring.”
