iron (English)
Where does "iron" come from?
The English word 'iron' descends from the Old English 'īsern,' which evolved from Proto-Germanic and Proto-West Germanic roots. These Germanic terms were borrowed from Proto-Celtic, which itself likely derived the word from a Proto-Indo-European root meaning 'blood,' possibly referring to the reddish hue of iron ore. Over centuries, the word underwent phonological changes, such as the loss of 's' in Middle English, to become the common term we use today.
