nine (English)

Where does "nine" come from?

The English word 'nine' traces its roots back to the Proto-Indo-European term '*h₁néwn̥'[1]. It passed into Proto-Germanic as '*newun'[1][4] and later into Proto-West Germanic as '*neun'[1][6]. Old English adopted the form 'nigon'[1][2], which eventually evolved into the Middle English 'nyne'[1][5]. This numerical term shares a common ancestry with many other languages, such as the Latin 'novem', Sanskrit 'náva', and Ancient Greek 'ἐννέα'[1].
