Feminism is having a moment: Everyone from Barack Obama to Ivanka Trump is hopping on the bandwagon. While the rising profile of women's rights is great, it gets hard to separate the heart-felt feminists from the trendy ones. For a decisive definition of the buzzword, Revelist turned to Chimamanda Ngozi Adichie — the award-winning Nigerian author who once taught Beyoncé what feminism means. 

Revelist asked Adichie for her definition of a true feminist at a United Nations event on August 19.

"Being a feminist means having a major problem with the way gender functions in the world," she responded, "and not just having a problem, but wanting to fix it; wanting to act."

And act she has: In the last three years, Adichie wrote a book exploring race and gender in America, skewered the Trump campaign in a story for The New York Times Book Review, and gave a TED Talk on feminism that's been seen almost 3 million times.

She also recently spoke out against sexism in the presidential election. In an interview with People, Adichie said it's gender-biased for commentators to call Hillary Clinton robotic and uncharismatic, and criticize her for not smiling enough.

"There's a lot that goes into the way that the public engages with her that would not happen if she weren't a woman," she told People.

However, the thing she's most disappointed about in this election has nothing to do with sexism.

"I just feel bad that Hillary Clinton doesn’t have a real, proper opponent, because I think she deserves one," she told Revelist.

Adichie believes winning against a proper opponent would be a much more "delicious" victory for the first female major party nominee. But the "Americanah" author said she is confident that Clinton will be the next president, no matter how unsatisfying the victory may be. 

Revelist spoke with Adichie before she gave the keynote speech at the UN's World Humanitarian Day's "One Humanity” event on Friday, less than two months after giving birth to her first child. 

The MacArthur genius grant-recipient has been notably quiet about her pregnancy, but she spoke candidly with Revelist about how motherhood has changed her perspective of the world.

"It just makes you really long for all the cliché things we talk about: peace in the world, justice and such," she said. "Because suddenly you love someone else more than yourself and you want the world to be a better place for that person."

And if there's anyone who can make the world a better place, we'd put our money on Adichie.
