Why don't you conjugate abrir when asking “can you open the door?” in spanish can someone please explain this?

The Spanish verb abrir nearly always works as the equivalent of "to open" or "to open up." You can use abrir to refer to the opening of a diverse array of things such as doors, stores, nuts, containers, wells, curtains, books, and mouths. So you wouldn't need to conjugate it.

Explanation:

I'm better at japanese but I think I'm correct.

corras is the only one that is informal but doesn't follow the suffix rule. correr is the verb. corre is the formal verb form. corra would be used as the formal is corre ended with an a.

your best bet would be corras, it's the only one that is informal but is still wrong
