seed

Seed comes from Old English sēd or sǣd, meaning 'seed, that which is sown,' tracing back through Proto-West Germanic *sād and Proto-Germanic *sēdą to the Proto-Indo-European root *seh₁-, 'to sow, throw.'

The word has stayed remarkably close to its root meaning across the centuries — from Old English sēd to Middle English seed, sede, side, it has always named the thing that is sown.

It's cognate with Dutch zaad, German Saat, and Swedish säd, all meaning 'seed,' and shares its deep root with Latin serō, 'to sow,' the ancestor of the English word sow.
