Learn Spanish (Latin America): Con este blindaje nuevo, eres superinmune al fuego. - With this new armor, you are super-immune to fire.

In Spanish, prefixes like super-, re-, and hiper- are generally written attached directly to the word they modify. Unlike English, which often uses hyphens, you must write superinmune as one continuous word, without a hyphen or a space.

The immunity comes from the new armor, so it is a temporary state. Why use eres (from ser) instead of estás (from estar)?

Even though the armor temporarily grants the immunity, the phrase ser inmune is a standard combination in Spanish. Immunity is treated as a defining characteristic, classification, or trait of the subject, so it takes ser regardless of how or when it was acquired.

Would it change the meaning if I said este nuevo blindaje instead of este blindaje nuevo?

Yes, there is a subtle difference. Este blindaje nuevo (putting the adjective after the noun) emphasizes that the armor itself is brand newly made. Este nuevo blindaje (putting the adjective before the noun) would just mean it is a newly acquired armor for you, even if the item itself is second-hand or old.

Why do we use al (a + el) before fuego instead of another preposition like de?
