radix (English)

Where does "radix" come from?

The word radix traces back to the Proto-Indo-European root *wréh₂ds, which originally meant a root. It passed through Proto-Italic before entering Latin as rādīx, eventually reaching English as a learned borrowing. Interestingly, it is a linguistic sibling to the word radish, both sharing this ancient ancestral origin.
