💡 Grammar Points
Matching the Noun
Think of 'cuántos' as a chameleon. It changes to match the thing you're asking about. Use 'cuántos' only for masculine things you can count, like 'libros' (books) or 'amigos' (friends).
The Four Forms
This word has four forms: 'cuánto' (masculine singular), 'cuánta' (feminine singular), 'cuántos' (masculine plural), and 'cuántas' (feminine plural). Always pick the one that matches the noun.
❌ Common Pitfalls
Gender & Number Mismatch
Mistake: "Using 'cuántos' for feminine or singular things. For example: *¿Cuántos sillas hay?*"
Correction: The word for 'chairs' ('sillas') is feminine and plural, so you need to use the matching form: '¿Cuántas sillas hay?'
⭐ Usage Tips
Questions vs. Exclamations
The word 'cuántos' is the same for asking a question and making an exclamation. The only difference is the punctuation: question marks (¿?) for asking, and exclamation points (¡!) for showing surprise.

As a pronoun, 'cuántos' stands alone to ask 'how many' when the masculine, plural noun (like 'robots') is already understood from the context.

💡 Grammar Points
Standing in for a Noun
You use 'cuántos' this way when everyone already knows what you're talking about. It stands in for the masculine, plural noun so you don't have to repeat it.
❌ Common Pitfalls
Using the Singular Form
Mistake: "When asking about multiple people or things, sometimes learners use the singular form: *¿Cuánto vienen a la fiesta?*"
Correction: Because you're asking about multiple people (a plural concept), you need the plural form: '¿Cuántos vienen a la fiesta?'
⭐ Usage Tips
Answering the Question
When someone asks you a question with 'cuántos', you can often answer with just a number. '¿Cuántos quieres?' (How many do you want?) 'Quiero tres.' (I want three.)

Frequently Asked Questions
What's the difference between 'cuánto' and 'cuántos'?
Think of it like 'how much' vs. 'how many'. You use 'cuánto' for things you can't count easily, like water or time ('¿Cuánto tiempo?'). You use 'cuántos' for things you can count one-by-one, like books or friends ('¿Cuántos amigos?').
Why does 'cuántos' have an accent mark?
The accent mark is a signal that you're asking a question or making an exclamation (like 'How many?!'). The version without an accent, 'cuantos', is used for making statements, like 'Tengo cuantos necesito' (I have as many as I need).
