Another top trending word for 2017 was "complicit", connected to Trump's sacking of Federal Bureau of Investigation director James Comey, Russian interference in the 2016 election, and Ivanka Trump's comment that she did not know what the word meant - which was then parodied in a skit for television show "Saturday Night Live".
Merriam-Webster said interest in the term was driven by women's marches, new TV shows and films on women's issues and the string of news stories on sexual assault and harassment claims.
According to Merriam-Webster that word is "feminism".
It adds that it is also "organised activity on behalf of women's rights and interests". This is due to the fact many high-profile world events this year have focused on women's rights and gender equality, from the Women's Marches that took place around the globe at the start of 2017, to the United States presidential campaign between Donald Trump and Hillary Clinton to the recent #MeToo campaign in which women shared their accounts of sexual assault and harassment. Many wore pink knitted "pussyhats" in reference to controversial remarks Donald Trump was recorded making in 2005. The word spiked again when Kellyanne Conway said during an interview that she didn't consider herself a feminist.
She said she was a "product of my choices, not a victim of my circumstances", which she described as "conservative feminism". Merriam-Webster credits the Hulu series "The Handmaid's Tale" and the movie "Wonder Woman".
The term enjoyed multiple lookup spikes on the dictionary's website in 2017 and an overall 70 percent rise in its searches compared with 2016. In this case, the definition of feminism was itself the subject of the news story-an invitation for many people to look up the word.
Other events that caused feminism to spike included the increasing allegations of sexual misconduct against prominent men in politics, media and entertainment - most notably with regard to the #MeToo movement.
Searches rose following the Women's March on Washington and other U.S. cities on January 21, the day after Trump was sworn in as president, the dictionary said Tuesday.
