Definition of MTF (Entry 2 of 2)

: a transgender woman The descriptors male to female (MTF) and female to male (FTM) are often used in medical and sociological literature to describe trans people, and sometimes they use them to talk about themselves. Many trans people prefer the terms “trans man” (same as FTM) or “trans woman” (same as MTF) because these terms affirm their chosen identities.— Laura Erickson-Schroth, quoted in The New York Times, 21 Apr. 2010
