Which one should you use?
While pendejo is a common way to call someone an idiot, other terms may change the nuance. Idiota is the most direct translation of the English word 'idiot'. Tarado/a can be interpreted as 'imbecile' or 'moron', and estúpido/a is similar to calling someone 'stupid'. If you want to describe someone as stubborn or obstinate in a formal way, use necio/a.
Is there a formal and an informal way to say it?
Pendejo is highly informal and can be considered vulgar or offensive depending on the context. In contrast, necio/a serves as a formal expression to describe someone who is being stubborn.
Is it said differently in some regions?
In Mexico and parts of Latin America, pendejo is a common slang term for an idiot or a fool. In Argentina, the word boludo/a is used frequently among friends, though it can be offensive if used with strangers. In some specific contexts in the Southern Cone, pendejo can sometimes imply that someone is a coward or a 'punk' rather than just lacking intelligence.
How does it change in a sentence?
The word changes its ending to pendeja to refer to a female, and the plural form is pendejos.
