innecesario
/inneθeˈsaɾjo/ · B2 · adj
unnecessary
🗑️ in- (not) + necesario (necessary) = not needed, like English necessary
Innecesario splits into in- (not) and necesario (needed). The double n comes from in- meeting the n of necesario. If you know English necessary, you already have the root: not necessary means unnecessary.
