💡 Grammar Points
Adding Emphasis to Questions
You can slip 'diablos' into a question right after the question word (like qué, dónde, cuándo) to add a strong feeling of frustration or disbelief. For example, '¿Qué quieres?' is 'What do you want?', but '¿Qué diablos quieres?' is 'What the hell do you want?'.
❌ Common Pitfalls
Using in Formal Situations
Mistake: "Le dije a mi jefe, '¿Dónde diablos está el informe?'"
Correction: It's better to say, 'Disculpe, ¿dónde está el informe?'. 'Diablos' is too informal for the workplace and can sound disrespectful.

Frequently Asked Questions
Is 'diablos' a very offensive swear word in Spanish?
Not really. It's considered a mild swear word, similar to 'damn' or 'hell' in English. While you shouldn't use it in formal settings like a job interview, it's very common and generally acceptable in casual conversations among friends and family.
Can I use 'diablo' (singular) in the same way as an exclamation?
Yes, but it's less common. People more frequently use the plural form '¡Diablos!' as a standalone exclamation. However, the singular 'diablo' appears in many other idioms, like 'pobre diablo' (poor devil/soul) or 'el diablo sabe más por viejo que por diablo' (the devil knows more from being old than from being the devil - meaning wisdom comes with age).
