The Power of 'Des-'
In Spanish, adding 'des-' to the start of a word is just like adding 'un-' in English (like turning 'happy' into 'unhappy'). Here, it turns 'known' into 'unknown'.

Stranger vs. Strange
Mistake: “Using 'extraños' to mean people you haven't met yet.”
Correction: While 'extraños' can mean strangers, it often implies someone is 'weird' or 'strange.' If you just mean you don't know them, 'desconocidos' is the safer, more natural choice.
