⭐ Usage Tips
Sensitivity Warning
In modern discourse, especially in journalism and humanitarian contexts, using 'indocumentados' (undocumented) or 'personas sin papeles' (people without papers) is strongly preferred over 'ilegales' when referring to people, as it is seen as more humane and less judgmental.
