The Cambridge Dictionary announced in 2025 that more than 6,000 new words and phrases have been included to show the fast development of modern English. One of the most discussed additions is skibidi, a nonsense word from a popular animated YouTube series. It can mean “cool,” “bad,” or simply serve as a playful filler without clear meaning. Other new words include tradwife, short for “traditional wife,” describing a married woman who takes domestic roles and shares them online, and delulu, from “delusional,” which refers to holding unrealistic beliefs. Linguists explained that many of these words come from social media platforms such as TikTok, which strongly influence how young people communicate.

The dictionary stated that new entries are selected through study of the Cambridge English Corpus, a database with billions of examples of written and spoken English. This tool helps experts measure how often new words appear and how they are used. Some recent entries reflect social and environmental concerns, including mouse jiggler, a device that makes it appear someone is working during remote tasks, and forever chemical, a harmful substance that stays in the environment for long periods. Specialists highlighted that the dictionary records language as it is used, not as it should be used. Colin McIntosh, lexical program manager, stressed that only words with clear staying power are chosen, showing the vibrancy and volatility of today’s English.
