Rule reminder
Italian has several contrast connectives with different nuances. Mentre (while/whereas) contrasts two simultaneous or parallel situations. D'altro canto (on the other hand) presents a different angle on the same subject. Al contrario (on the contrary) refutes or inverts a previous statement. Invece (instead/on the other hand) implies an unexpected or substitutive contrast.
