Merriam-Webster says its word of the year is 'hard to define and subject to debate' – and has something to do with Taylor Swift

• Merriam-Webster chose "authentic" as its word of the year, and cites Taylor Swift as a factor.
• The dictionary publisher also said AI played a role by blurring the lines between "real" and "fake."
• Other entries include "rizz", "dystopian," "X," and "implode," all driven by news events this year. 

Merriam-Webster announced its words of the year on Monday and no, AI doesn't top the list. 

Instead, the dictionary publisher picked "authentic" as the top word of the year. 

"Although clearly a desirable quality, 'authentic' is hard to define and subject to debate," Merriam-Webster said.
