Questions & Answers about C'è uno sbaglio sullo schermo.
Why do we use sullo instead of sul for "on the"?
Sullo combines the preposition su (on) and the definite article lo (the). We must use lo here because schermo is a masculine noun starting with an 's' plus a consonant ('c'). If the word started with a regular consonant, we would use il, and the combined word would be sul.
Does uno sbaglio follow the same rule as sullo schermo?
Is it okay to write su lo schermo as two separate words?
No, in Italian, you must combine the preposition su with the definite article that follows it. Writing su lo separately is grammatically incorrect; they must always merge into the single word sullo.
