Merriam-Webster says feminism is their 2017 word of the year. It was chosen based on having the most lookups.
In a statement, Merriam-Webster said feminism showed a 70% increase over 2016 and it experienced several spikes in lookups in connection to news reports or events in 2017. Feminism lookups increased in the last weeks of January following news coverage of the Women’s March on Washington, D.C. Interest spiked again in February, when Kellyanne Conway said during an interview that she didn’t consider herself a feminist. Merriam-Webster also saw lookups go up after the release of Hulu’s series, “The Handmaid’s Tale” and the movie, “Wonder Woman.” More recently, as you can imagine, lookups of feminism increased with reports of sexual assault and harassment in the news.
In case you are curious, the Merriam-Webster's definition is, “the theory of the political, economic, and social equality of the sexes” and “organized activity on behalf of women's rights and interests.”
Other notable words of 2017 are: complicit, recuse, empathy, dotard, syzygy, gyro, federalism, hurricane and gaffe.
