💡 Grammar Points
A Word That Doesn't Change
'Alias' is special because it is invariable: it stays exactly the same whether you are talking about one alias ('el alias') or many aliases ('los alias').
❌ Common Pitfalls
Don't Add an 'es'
Mistake: "Los aliases (Incorrect plural form)"
Correction: The correct plural is simply 'los alias'. Remember, the word already ends in 's' and doesn't follow the usual plural rules.
⭐ Usage Tips
Formal vs. Informal Nicknames
Use 'alias' when the name is assumed or used to disguise identity (often negative context). Use 'apodo' or 'sobrenombre' for a friendly, common nickname.

Frequently Asked Questions
What is the difference between 'alias' and 'apodo'?
'Apodo' (nickname) is a name commonly given to someone by friends or family, usually based on a physical trait or personality (e.g., 'Flaco' for a thin person). 'Alias' is a name someone chooses for themselves, usually to hide their real identity or for professional reasons (like a writer's pseudonym or a criminal's assumed name).
Is 'alias' only used for criminals?
No, although it is often associated with crime in the news, it can be used for anyone who uses an assumed name, such as a spy, a hacker, or an author using a pen name.
