✦Grammar Breakdown

Definite article agreement
The article "La" must agree in gender and number with the noun "biblioteca" (feminine singular).
Ser vs. Estar
Use "es" (ser) to identify what something is, not where it is; "está" would refer to location.
Demonstrative adjective "ese"
"Ese" points to something that is relatively farther from the speaker but close to the listener.
Adjective "gran" before a noun
When "gran" (great/big) precedes a noun, it drops the final "o" of "grande".
Noun phrase "edificio de piedra"
The prepositional phrase "de piedra" works like an adjective, describing the material of the building.
Question formation
Spanish questions are marked by inverted punctuation (¿) at the beginning and a regular question mark at the end.

✕Common Mistakes
¿La biblioteca está ese gran edificio de piedra?
Use "es" (ser) for identity; "está" would incorrectly ask about location.
¿La biblioteca es este gran edificio de piedra?
"Este" points to something close to the speaker; here the building is farther, so "ese" is correct.
¿La biblioteca es ese grande edificio de piedra?
Do not use "grande edificio"; when "grande" precedes a noun it becomes "gran".

Cultural Tip
In Spanish, "ser" is used for essential identity (what something is) while "estar" describes temporary states or locations. Also, "gran" is the shortened form of "grande" used only before a noun, which is a common source of confusion for learners. When pointing at something far from you but near the listener, "ese" is the appropriate demonstrative; "este" would be used for something close to you.
