Sen. Elizabeth Warren’s bio on her official presidential campaign Twitter page is touting a new addition: her pronouns. Earlier this month, her bio was updated to "U.S. Senator, former teacher, and candidate for president. Wife, mom ... grandmother, and Okie. She/hers. Official campaign account." She is one of three 2020 presidential hopeful to add pronouns on an official campaign Twitter account, along with Julian Castro and Bill de Blasio.

On the surface, it’s just two words. But the inclusion of “she/hers” on a major candidate’s social media profile is no small feat in the eyes of LGBTQ advocates. Among the LGBTQ community and its allies, including pronouns in social media profiles has become increasingly common to avoid misgendering and to indicate solidarity with transgender and nonbinary people.

In a statement provided to NBC News, Warren campaign spokesperson Alexis Krieg said of the profile change: “Elizabeth is committed to running an inclusive campaign, and wants every person to know that they are welcome in this movement.”

Warren, from Massachusetts, has been outspoken on the subject of LGBTQ rights, and she tweeted her support in May for the Equality Act — a bill that would add “sexual orientation” and “gender identity” to the classes protected against discrimination by federal civil rights law. In her tweet, she stated, “nobody should be discriminated against for who they are or who they love.”

Lucas Acosta, a spokesperson for the Human Rights Campaign, a national LGBTQ advocacy group, said adding pronouns to bios “is a best practice for all campaigns at every level.”

"Stating your pronouns publicly as a cisgender ally sends a strong signal of support to the LGBTQ community but particularly transgender and nonbinary people that they are seen, accepted and supported,” Acosta told NBC News in an email.

Mathew Lasky, director of communications at GLAAD, a national LGBTQ media watchdog group, echoed Acosta’s statement.

“Politicians identifying and expressing their pronouns is a great representation of how to establish inclusive spaces for dialogue with potential voters,” he said. “As more people identify beyond the binary of male and female, identifying your pronouns in conversation is not only a great way to educate mainstream audiences about gender identity, but also to show conscious support for the LGBTQ community.”

On its “Tips for Allies of Transgender People” page, GLAAD advises that you can’t tell if someone is trans just by looking at them, and the organization recommends against assuming someone’s pronouns. “If you accidentally use the wrong pronoun, apologize quickly and sincerely, then move on,” it states.

As Warren polls toward the front of a crowded field, she could square up in 2020 against President Donald Trump, whose actions — including an attempted ban on transgender service members in the military — have caused outcry among LGBTQ advocates.

But for now, Warren is set to take to the presidential debate stage on July 30, where she’ll be joined by nine other Democratic hopefuls, including Sen. Bernie Sanders of Vermont and Mayor Pete Buttigieg of South Bend, Indiana. It remains to be seen if the debates will reveal more about the candidates’ platforms on LGBTQ rights.
