três (Portuguese)
Where does "três" come from?
The Portuguese word 'três' traces its lineage back to the Proto-Indo-European root *tréyes. It evolved through Proto-Italic and Latin as 'trēs' before passing into Old Galician-Portuguese and finally arriving at its modern form. This ancient numerical term has remained remarkably consistent in form and meaning across millennia of linguistic evolution.
