NEW YORK TIMES BESTSELLER • From linguist Adam Aleksic, known as @etymologynerd on social media, comes a captivating exploration of how internet algorithms are transforming language and communication in unprecedented ways.

“Packed with fascinating facts, of-the-moment observations, and a sparkling voice, Algospeak is a gift to any word nerd. Deftly covering everything from emoji etymologies and trendbait to Taylor Swift fanilects... Adam Aleksic is the wise, yet accessible internet linguistics oracle we need.”—Amanda Montell, author of The Age of Magical Overthinking and Cultish

From “brainrot” memes and incel slang to the trend of adding “-core” to different influencer aesthetics, the internet has ushered in an unprecedented linguistic upheaval. We’re entering an entirely new era of etymology, heralded by the invisible forces driving social media algorithms. Thankfully, Algospeak is here to explain. As a professional linguist, Adam Aleksic understands the gravity of language and the way we use it: he knows the ways it has morphed and changed, how it reflects society, and how, in its everyday usage, we carry centuries of human history on our tongues. As a social media influencer, Aleksic is also intimately familiar with the internet’s reach and how social media impacts the way we engage with one another. New slang emerges and goes viral overnight. Accents are shaped or erased on YouTube. Grammatical rules, loopholes, and patterns surface and transform language as we know it. Our interactions, social norms, and habits—both online and in person—shift into something completely different.

As Aleksic uses original surveys, data, and internet archival research to usher us through this new linguistic landscape, he also illuminates how communication is changing in both familiar and unexpected ways. From our use of emojis to sentence structure to the ways younger generations talk about sex and death (see unalive in English and desvivirse in Spanish), we are in a brand-new world, one shaped by algorithms and technology. Algospeak is an energetic, astonishing journey into language, the internet, and what this intersection means for all of us.
