This Is The Merriam-Webster Dictionary Word of the Year
The Merriam-Webster Dictionary is something I use all the time. It's important to spell words correctly in my job, so their online directory is pretty handy.
If you are wondering what word was looked up more than any other for 2017, that would be 'Feminism'. I personally would have thought it was #metoo, but it's pretty darn close. According to the dictionary folks, 'Feminism' was looked up 70% more than last year, and we're guessing that had to do with so many major women's issues this year, including the Women's March on Washington.
The actual definition of the word is 'the theory of the political, economic, and social equality of the sexes' and 'organized activity on behalf of women's rights and interests'
