Cambridge Dictionary has officially added thousands of new words, including viral internet terms that have dominated social media conversations in recent years.

The prestigious dictionary announced its latest additions today, featuring words that reflect the evolving landscape of online communication and cultural trends.

Skibidi – The viral term originating from the bizarre “Skibidi Toilet” YouTube series has earned its place in formal English recognition

Delulu – Gen Z’s favourite way to say “delusional,” often used playfully to describe unrealistic expectations or over-the-top behaviour.

The dictionary defines delulu as a shortened form of “delusional,” describing someone who is clueless or unable to figure out a practical solution in a given situation. This reflects how Gen Z and millennials have adapted language to express complex feelings in simplified, catchy forms.

Tradwife – Short for “traditional wife,” describing women who embrace conventional homemaking roles and promote this lifestyle on social media

Broligarchy – A blend of “bro” and “oligarchy,” pointing to male-dominated power structures in business and politics

The additions highlight how quickly internet slang transitions from niche online communities to mainstream usage. Language experts at Cambridge note these terms have shown consistent usage across social media platforms, news outlets, and everyday conversation.

“These words reflect how we communicate in 2025,” a Cambridge spokesperson explained. “From TikTok trends to societal discussions about gender roles, our language continues to evolve at unprecedented speeds.”

The move follows similar updates by other major dictionaries, as institutions race to keep pace with rapidly changing linguistic landscapes driven by social media and digital communication.
