From an AP story by Leanne Italie headlined “Gaslighting is Merriam-Webster’s word of the year”:

“Gaslighting” — behavior that’s mind manipulating, grossly misleading, downright deceitful — is Merriam-Webster’s word of the year.

Lookups for the word on merriam-webster.com increased 1,740% in 2022 over the year before. But something else happened. There wasn’t a single event that drove significant spikes in curiosity, as it usually goes with the chosen word of the year.

The gaslighting was pervasive.
