teorema

theorem

noun teh-oh-REH-mah Rare

Origin: From Greek theorema (speculation, proposition), from theorein (to look at).

Usage Note

Teorema ends in -ma but is masculine — il teorema, not la teorema — a pattern shared with other Greek-origin nouns like il problema and il sistema. The plural is i teoremi. It refers exclusively to a formally proved mathematical or logical statement.

Examples

"Il teorema di Pitagora è fondamentale."

Natural Translation

Pythagoras's theorem is fundamental.
