Questions & Answers about Siempre corro por esta ruta.
Why do we use por here instead of para?
Could por esta ruta also mean "because of this route"?
Wait, doesn't está mean "is"? Why does it mean "this" here?
You are thinking of está with an accent mark, which comes from the verb estar (to be). Without the accent mark, esta is the feminine word meaning "this", which matches the feminine noun ruta.
Why is it esta ruta and not esto ruta?
Ruta is a feminine noun, so it needs the feminine word for "this", which is esta. You only use esto when you are talking about a general idea, an entire situation, or an unknown object, and it is never placed directly in front of a noun.
