Learn Spanish (Latin America): ¡Qué campeón tan nervioso!

In Spanish, the exclamatory word qué (when it means "what a...") connects directly to the noun. You never use the indefinite articles un or una after qué in this kind of exclamation.

Why is the word order campeón tan nervioso instead of nervioso campeón?

In English, we put the adjective first ("What a nervous champion!"). In Spanish exclamations, the standard pattern is ¡Qué + [noun] + tan + [adjective]!. It literally translates to "What a champion so nervous!" You will also often hear más used instead of tan here (¡Qué campeón más nervioso!) with the exact same meaning.

If tan usually means "so," why isn't it translated in the English meaning?

In the ¡Qué... tan...! structure, tan is just there to intensify the adjective, similar to how we use vocal emphasis in English. A natural English translation wraps this all up into "What a [adjective] [noun]!" rather than awkwardly saying "What a champion so nervous!"

Why does campeón have an accent mark? Does the plural have one too?
