Questions & Answers about Chiudo la porta blindata perché nessun intruso entri.

Why does this sentence use the subjunctive entri after perché, rather than the indicative entra?

In Italian, perché usually means "because" and takes the indicative. However, when it means "so that" or "in order to" (expressing a purpose or goal), it triggers the subjunctive. Here, you are closing the door so that no intruder enters, not because no intruder is entering.

Doesn't Italian usually use double negatives? Why is there no non before entri?

When negative words like nessun (or nessuno, mai, nulla) are placed before the verb, you do not use non. You only use the double negative structure if the negative word comes after the verb, which would look like this: perché non entri nessun intruso.

Why is it nessun intruso without an apostrophe, even though intruso starts with a vowel?

The adjective nessuno follows the same spelling rules as the article uno. Before a masculine noun starting with a vowel, it drops the final -o to become nessun (with no apostrophe). You only use an apostrophe before feminine nouns, when nessuna drops its -a (like nessun'amica).

Is a porta blindata something you'd only see in a bank or military base?
