Learn Italian: Non ti impedisco mica di uscire senza consenso! - I am not preventing you from going out without consent!

Senza che is used when you are introducing a new clause with a new subject and a verb. In this sentence, senza is simply followed by a noun (consenso), so we just use the preposition senza without che or the subjunctive.

What does the word mica add to this sentence?

Mica is a common spoken word used to strongly emphasize a negative statement. It often translates to English phrases like 'not at all' or 'it is not like'. By saying Non ti impedisco mica, the speaker is correcting a false assumption, meaning 'It is not like I am preventing you!'

Why is ti used before impedisco? Is it a direct object?

No, ti is an indirect object pronoun here. The verb impedire follows the pattern impedire a qualcuno di fare qualcosa (to prevent someone from doing something). So in Italian logic, you are preventing the going out 'to' someone.

Why do we need the preposition di before uscire?

Many Italian verbs require a specific preposition to connect them to a following infinitive verb. Because the pattern is impedire a qualcuno di fare qualcosa, you must use di to link the main verb directly to the action of going out.
