Hi Erol,
In Italian, whether you use "di", "da", or nothing at all before an infinitive depends on the verb or structure that comes before it. Here’s a breakdown to help:
✅ When to use "da" before the infinitive
"Da" is often used after nouns to express purpose — it’s like saying "to do something" or "for doing something."
Vuoi qualcosa da mangiare? → Do you want something to eat?
(“Something for eating” – purpose)
Ho bisogno di un posto da dormire. → I need a place to sleep.
You’ll usually see “da + infinitive” after nouns like qualcosa, niente, molto, poco, or tempo, when expressing the idea of a purpose.
✅ When to use "di" before the infinitive
"Di" is used after many verbs, adjectives, or expressions that are followed by an infinitive.
Penso di partire domani. → I plan to leave tomorrow.
Spero di vederti presto. → I hope to see you soon.
Sono felice di essere qui. → I'm happy to be here.
Unfortunately, there’s no strict rule — you have to memorize which verbs or phrases take "di."
✅ When NOT to use a preposition
Some verbs are directly followed by the infinitive — no "di" or "da" needed.
Non vogliono mangiare niente. → They don’t want to eat anything.
Mi piace leggere. → I like to read.
These verbs include: volere, potere, dovere, sapere, piacere, preferire, etc.
Recap:

Let me know if you’d like a list of common verbs that take "di" or none at all, happy to help! 😊
