Oxford Dictionaries declared the word that exemplifies the "ethos, mood, or preoccupations" of 2018 is "toxic" on Friday, according to The Washington Post.
The online dictionary said it decided the word was the most likely to "have lasting potential as a term of cultural significance."
“In 2018, toxic added many strings to its poisoned bow becoming an intoxicating descriptor for the year’s most talked about topics,” wrote Oxford Dictionaries.
The organizers said some of the runners-up for this year included "gaslighting," which stems from a 1938 play that means "the action of manipulating someone by psychological means into accepting a false depiction of reality or doubting their own sanity."
The dictionary said the term was frequently used to describe tactics employed by United States President Donald Trump and his staff, pointing to how White House adviser Kellyanne Conway used "alternative facts" to describe Trump's interpretation of events.
The Oxford Dictionary also said the term has been applied to the Conservative government's treatment of Brexit with the United Kingdom.
