Frequently Asked Questions
How do I know if 'locos' means 'crazy people' (noun) or just 'crazy' (adjective)?
If 'locos' has an article (like 'los' or 'unos') directly in front of it, it is usually acting as a noun ('Los locos llegaron' - The crazy people arrived). If it comes after a form of 'ser' or 'estar' and describes a subject, it's an adjective ('Ellos son locos' - They are crazy).
Can I use 'locos' if the group includes both men and women?
Yes. If you are describing a mixed-gender group (e.g., brothers and sisters), the masculine plural form ('locos') is always the correct standard choice in Spanish.
