Merriam-Webster is giving its dictionary another glow-up by officially adding 1,400 new words and definitions.

The publisher announced the major update on Tuesday, bringing popular internet terms like “looksmaxxing,” “meme coin,” and “parasocial” into the official record.

The company said the new entries reflect words that have gained widespread use over time and offer a window into today’s world.

Just in time for colder weather, the dictionary now includes “cuffing season,” along with AI-related terms like “vibe coding” and “uncanny valley.”

This focus on artificial intelligence follows the company’s 2025 Word of the Year, “slop,” which described low-quality, AI-generated digital content.

Merriam-Webster has not yet announced its Word of the Year for 2026, but the publisher typically reveals that big choice during the final months of the year.
