Learn Spanish (Latin America): Hasta el manubrio está mojado por el sudor. - Even the handlebar is wet from the sweat.

Yes, you can use incluso here without changing the core meaning. Both hasta and incluso act as scalar adverbs meaning "even." However, hasta originally means "until" or "up to," so it often adds a slightly stronger visual sense of reaching a limit—perfect for emphasizing that the sweat reached all the way to the handlebar.

Why use por here instead of de (mojado de sudor)?

Both are grammatically correct, but they have a slightly different feel. Using por points to the sweat as the cause—the handlebar is wet because of the sweat. If you used de (mojado de sudor), it would describe what the object is covered with, similar to how we say cubierto de nieve (covered in snow).

Why is it está mojado and not es mojado?

We use estar with past participles (like mojado) when describing a physical state or the result of an action. The handlebar is currently in a wet state. If you used ser, it would either describe a permanent characteristic or form the true passive voice (meaning someone is actively wetting it right now), neither of which makes sense here.

In English we usually just say "wet from sweat", so why does Spanish add the el in el sudor?
