Influencer

There’s certainly been a boom of influencers in the last couple of years, usually associated with Instagram. But the word itself isn’t all that modern a creation – according to multiple dictionary sites, the combination of “influence” and the suffix “-er” as a word dates back to the 1660s! Of course, back then, it wasn’t a job; it was used to more generally describe an influential person or circumstance (and still is today!). For instance, “Money was the biggest influencer on her decision to change careers.”
OMG

This shorthand for “oh my God,” a favourite lingo choice of schoolkids and texters of all ages, dates back about a hundred years! The Oxford English Dictionary recorded a use of it in 1917, in a letter from an admiral (a 76-year-old admiral, no less) to Winston Churchill. His use of the term and emphatic style, combined with the stately British language, seems downright anachronistic: “I hear that a new order of Knighthood is on the tapis – O.M.G. (Oh! My God!) – Shower it on the Admiralty!!” (Yes, he explained what “O.M.G.” stood for.)
We doubt all of these text abbreviations you should know have such distant origins.
Unfriend

Surprisingly and hilariously, this verb actually dates back to long before the advent of Facebook. Back before the days of social media – way back, in the 1600s – this word simply meant ending a friendship with someone. “I hope, Sir, that we are not mutually Un-friended by this Difference which hath happened betwixt us,” scholar Thomas Fuller wrote in 1659. Also hilariously, “unfriend” was actually used as a noun before people began using it as a verb! Sure enough, it meant “enemy,” in a rather cheeky shorthand for “the opposite of a friend.”
