In August 2025 there was quite a stir online and in news programs about the new words that the Cambridge Dictionary had added to its publication. Eyebrows were raised at the inclusion of skibidi, dululu, and tradwife (among others). These imposters from social media had some commentators bemoaning the imminent death of the English language.
The event raised the question: what is the purpose of a dictionary? The answer isn’t as easy as you might think. There are two broad answers you will generally find: a dictionary is either prescriptive or descriptive. In other words, it either tells you what words are correct and how they should be used (prescriptive) or it tells you how words are being used at the moment or at the time of writing (descriptive).
Most lexicographers would agree that the purpose of a dictionary is to describe and record how words are used. And this is what the new Cambridge dictionary is doing—capturing how the language is used at a specific moment in time.
