Ciao! When using the simple prepositions "di, a, da, in, su" with a definite article afterwards - we make a "Combined Preposition". For a helpful table we have an overview of all the combinations here! https://payhip.com/b/tpNsi :) .. Examples of combinations with di: La bicicletta del ragazzo. La bicicletta della ragazza. I libri degli studenti. With in: Parlo nel negozio. Compra il caffè nella caffetteria. Legge nello studio. Try: there is a cat in the house. there's a cup on the table.  he writes to the friend. he buys coffee to the friends.
