rotten (English)

Where does "rotten" come from?

The word 'rotten' traces its roots back to the Proto-Germanic root *rutāną, which meant 'to rot,' a term rooted in the deeper Proto-Indo-European concept of tearing or rending something apart. The modern English form evolved through Middle English 'roten' and was heavily influenced by the Old Norse 'rotinn.' While it originally described the physical state of decay, the word's meaning expanded over time to encompass moral failings and poor quality.
