Questions & Answers about Todavía no hemos comprado los vehículos. No están armados.
Why use están here instead of son for "they are"?
Estar is used with a past participle (like armados) to describe a physical condition or state that is the result of a previous action. We are talking about the current status of the vehicles (they are not armed right now), rather than a permanent characteristic. This combination of estar + past participle is called the stative passive.
Why does the past participle armados end in -os here?
Normally, when you use a past participle in a compound tense (like hemos comprado), it always ends in -o. But when it is used with estar to describe a state, it acts just like an adjective. This means it must match the noun it describes in gender and number. Because it describes los vehículos (masculine plural), it becomes armados.
Can I separate todavía and no, or do they have to stay together?
