💡 Grammar Points
Matching the Noun
Like many describing words in Spanish, 'tonto' changes to match the person or thing it's describing. Use 'tonto' for masculine things ('el niño tonto') and 'tonta' for feminine things ('la idea tonta'). For groups, use 'tontos' or 'tontas'.
❌ Common Pitfalls
Forgetting to Change the Ending
Mistake: "La chica es tonto."
Correction: Say 'La chica es tonta.' Describing words almost always need to match the gender (masculine/feminine) of the noun they describe.
⭐ Usage Tips
Tone is Everything
'Tonto' can be a lighthearted, affectionate way to call someone 'silly'. For example, '¡Ay, tonto, me asustaste!' (Oh, you silly thing, you scared me!). But the same word said with an angry tone can be a serious insult.

When used as a noun, tonto refers directly to a person who is a fool or simpleton.

💡 Grammar Points
Used as a Label
When you use 'tonto' as a noun, you are directly calling someone a fool. It's often preceded by 'un' or 'el' (e.g., 'Es un tonto'). Remember to use 'una tonta' or 'la tonta' for a female.
⭐ Usage Tips
Use with Caution
Calling someone 'un tonto' is much stronger and more direct than describing their action as 'tonta'. It's a personal label and can easily cause offense, so be careful how you use it.

Frequently Asked Questions
Is 'tonto' always an insult?
Not at all! It's all about tone and context. Between friends or loved ones, calling someone 'tonto' or 'tonta' can be a playful and affectionate way to say 'you're being silly'. However, if said with anger or in a serious situation, it is definitely an insult, similar to calling someone 'stupid' or an 'idiot'.
What's the difference between 'ser tonto' and 'estar tonto'?
'Ser tonto' describes a permanent characteristic, like saying someone *is* a foolish person in general. 'Estar tonto' describes a temporary state, like saying someone is *acting* foolish or silly right now. For example, 'Hoy estoy un poco tonto, no me puedo concentrar' (I'm being a bit silly today, I can't concentrate).
