permutation (English)

Where does "permutation" come from?

The word 'permutation' traces back to the Proto-Indo-European root *meyth₂-, meaning 'to exchange.' It evolved into the Latin permūtāre, signifying a thorough change, before passing through Old French and Middle English as the noun 'permutacioun.' Today, the term retains this core sense of alteration while specifically describing the various ways a set of items can be arranged.
