Questions & Answers about ¡Qué mercado! Está tan lleno que no podemos caminar.

Why do we use tan lleno instead of tanto lleno?

In consecutive clauses of intensity, you use tan (so) before adjectives like lleno (full) and before adverbs. You only use tanto (so much or so many) when modifying a noun (like tanta gente) or when it comes right after a verb.

Why does it say ¡Qué mercado! without an article like un?

In English, we say "What a market!" but Spanish drops the article in exclamations with qué followed by a singular noun. Saying ¡Qué un mercado! is grammatically incorrect. You simply attach the noun directly to qué.

Could we use es instead of está for tan lleno?

No, the adjective lleno (full) is always used with estar. This is because being full is a temporary state or condition, not an innate characteristic. It describes the specific state the market is in right now.

Since there is a que joining the clauses, why don't we use the subjunctive for podemos?

In consecutive clauses like tan [adjective] que... (so [adjective] that...), the second part of the sentence declares a real, factual result of the intensity. Because you are stating a fact that is actually happening as a consequence—you literally cannot walk right now—you use the indicative podemos.
