Learn Italian: Non possiamo parcheggiare qui, è tutto bloccato. - We cannot park here, everything is blocked.

Possiamo comes from the modal verb potere (to be able to / can). In Italian, modal verbs like potere, volere (to want), and dovere (must) connect directly to the next verb in its infinitive form without needing any prepositions in between.

How does tutto work in the phrase è tutto bloccato?

Here, tutto is used as a pronoun meaning 'everything.' When used this way, it acts as a masculine singular subject, which is why the describing word bloccato ends in -o to match it.

Could I use qua instead of qui?

Yes, you can! Both qui and qua mean 'here' and are mostly interchangeable. Qui sometimes indicates a more exact, specific spot, while qua can imply a slightly broader area, but in this context, either works perfectly.

Is bloccato a verb or an adjective here?

It is the past participle of the verb bloccare (to block), but here it functions as an adjective describing the current state of things ('blocked'). Because it acts as an adjective for tutto, it must agree in gender and number, remaining in the masculine singular form.
