Learn Hardcore Spanish (Spain): El partido político ganó un escaño. - The political party won one parliamentary seat.

Partido by itself can mean several things in Spanish, such as a match/game, a party, or something divided depending on context. Adding político makes it completely clear that we mean a political party.

In real context, Spanish speakers will often just say el partido if it is already obvious they are talking about politics.

Why does político come after partido?

In Spanish, descriptive adjectives usually come after the noun, unlike in English.

So:

partido político = political party
literally: party political

This is the normal word order here.

What does ganó tell me about the tense?

Ganó is the preterite form of ganar for él/ella/usted.

That means it refers to a completed action in the past:

ganó = won

So the sentence presents the winning of the seat as a finished event.

Why is it ganó and not ha ganado or ganaba?
