Proto-Celtic

Etymology

Probably from Proto-Indo-European *h₁ēsh₂r̥no- (“bloody, red”), from *h₁ésh₂r̥ (“blood”), but the long ē (which regularly became ī in Proto-Celtic) is unexplained. A connection with *ish₂ros (“supernatural, holy”) (compare Ancient Greek ἱερός (hierós, “supernatural, holy”), Sanskrit इषिर (iṣira, “refreshing”)) is also possible, though here too the long ī (which is confirmed by the Proto-Germanic loanword *īsarną) is unexplained.

Noun

*īsarnom n

1. iron
