The Oxford English Dictionary added 1,200 new words this week, including gender-fluid.
The venerated keepers of the English language define the term as “(a) (in early use) not clearly or wholly male or female; androgynous; (b) designating a person who does not identify with a single fixed gender; of or relating to a person having or expressing a fluid or unfixed gender identity (now the usual sense).”
Editor Katherine Martin told Time that of all the evolutions going on in the English language, she sees the “speed at which the English language is expanding” to accommodate identities like gender-fluid to be the most thrilling.
Other new additions include bracketology, ‘Merica, moobs, slacktivism, swirlie, vom and YOLO.
