Questions & Answers about Esta circunscripción es grande.

Why is it esta and not este?

Because circunscripción is a feminine singular noun, and the demonstrative has to agree with it.

• este = masculine singular
• esta = feminine singular

So:

• este distrito
• esta circunscripción

How do I know that circunscripción is feminine?

You learn its gender as part of the noun: la circunscripción.

There is also a very helpful pattern here: nouns ending in -ción are almost always feminine in Spanish.

Examples:

• la nación
• la elección
• la administración
• la circunscripción

So once you see -ción, feminine is a very good guess.

Why is there no article before circunscripción?

Because esta is already acting as the determiner.

In English, this already fills that slot, and the same is true in Spanish:

• esta circunscripción = this constituency / this district

You normally do not say la esta circunscripción in standard Spanish. It is either:

• la circunscripción = the constituency
• esta circunscripción = this constituency
