théorème (French)
Where does "théorème" come from?
The word 'théorème' entered French through the Middle French and Latin 'theorema,' originating from the Ancient Greek 'theṓrēma,' which denoted a proposition to be proved or a spectacle. It is rooted in the Greek verb 'theōréō,' meaning 'I look at' or 'contemplate,' which itself grew from the idea of being a spectator watching a show. Ultimately, the term evolved from the literal act of seeing or viewing into the mathematical sense of a truth that has been clearly perceived and proven.
