opt (Romanian)

Where does "opt" come from?

The Romanian word 'opt' descends from the Latin 'octō', which traces back to the Proto-Indo-European root '*oḱtṓw'. Remarkably, this ancient term was originally a dual form referring to 'two times four' fingers, reflecting an early human counting system based on sets of four.
