Mistake: “Applying this meaning without clear context, confusing the listener whether you mean 'incredibly talented' or 'incredibly cruel.'”

The 'Demonios' Expression
When used in questions like '¿Qué demonios dices?' (What the heck are you saying?), 'demonio' acts as an intensifier, showing annoyance or surprise, similar to saying 'hell' or 'heck' in English.
Literal Translation
Mistake: “Using 'demonio' in a formal setting just to mean 'very fast' or 'very hard.'”
Correction: Use this meaning only in informal or passionate conversations, as it is highly colloquial. In formal settings, use 'rápidamente' (quickly) or 'arduamente' (arduously).
