In 2025, the Cambridge Dictionary announced that more than 6,000 new words were added. One of the most popular is skibidi, a made-up word from a YouTube cartoon. It can mean “cool,” “bad,” or be used with no clear meaning, often as a joke. Other new words include tradwife, short for “traditional wife,” which describes a married woman who cooks, cleans, and shows this life on social media. Another new word is delulu, from “delusional,” which means believing things that are not true. Experts said that many of these new words spread through social media, especially TikTok, which is very popular with young people.

The Cambridge Dictionary said that word choices are based on the Cambridge English Corpus, a collection of billions of words from books, articles, and everyday conversations. This database shows how often people use words and in what situations. New terms also come from daily life. Mouse jiggler is a tool that makes a computer look busy during remote work, and forever chemical describes dangerous substances that stay in the environment for many years. Experts explained that the dictionary shows how people really use English, and only words likely to last are included.
