Frequently Asked Questions

Is 'casualidad' the same as 'luck'?

Not exactly. 'Casualidad' is the unexpected event itself (a coincidence). 'Luck' is 'suerte' and refers to the good or bad fortune resulting from the event. You can have a 'casualidad' (a chance meeting) that results in good 'suerte' (good luck).

Can I use 'casualidad' to describe someone's clothes?

No. When describing informal clothing, Spanish uses the adjective 'casual' (e.g., ropa casual). 'Casualidad' only refers to the concept of chance or coincidence.
