I had a look at new words being introduced into various dictionaries in 2025. This is the AI summary – so I don’t know how accurate it is – but they show the immense impact of social media. Previously they would probably have been from literature or movies.
Unlike Swedish (and French I believe), there is no body that regulates which words are officially recognised in English. Sweden has the Swedish Academy, whose wordlist is regarded as the definitive guide to the Swedish language. The Swedish Academy also awards the Nobel Prize in Literature.
I wonder what the shelf-life of a social media word is? I would imagine that trends come and go pretty quickly.
