nine

nine: [OE] Nine is part of a general Indo- European family of ‘9’-words, which trace their ancestry back to a prehistoric *newn or *enewn. Among the descendants of these are Greek ennéa, Latin novem (source of English November), Irish nóin, Lithuanian devynì, and Russian devyat’. Its Germanic forms *niwun or *nigun have differentiated into German neun, Dutch negen, Swedish nio, Danish ni, and English nine. Noon is so called from being originally the ‘ninth’ hour.
