Frequently Asked Questions

Is 'causas' always feminine?

When it means 'reasons' or 'legal cases', yes, it is feminine (las causas). When used as slang for 'friends' in Peru, people might say 'mis causas' for a group of friends regardless of gender.

How do I know if 'causas' is a noun or a verb?

Look at what comes before it! If you see 'las', 'muchas', or 'mis', it's likely a noun (things). If it follows 'tú' or is the main action of the sentence, it's a verb (you cause).
