💡 Grammar Points
Using 'de' after millón
When 'millón' is followed by the thing being counted (like people or cars), you MUST use the word 'de' (of): 'un millón de coches'.
Singular vs. Plural
The number itself stays singular when it is exactly one ('un millón'), but becomes plural ('millones') for any number greater than one (dos millones, cien millones).
❌ Common Pitfalls
Forgetting 'un'
Mistake: "Compré millón de libros. (I bought million of books.)"
Correction: Compré **un** millón de libros. (You need the number 'one' before 'million' because it acts like a noun.)
⭐ Usage Tips
Counting in Spanish
Unlike 'mil' (thousand), 'millón' acts like a regular noun. This means it needs the article 'un' or another counting word before it.

Informally, 'millón' can be used hyperbolically to mean 'loads' or 'a huge, uncountable amount.'

💡 Grammar Points
Idiomatic Use
When used to mean 'a lot,' it often appears in the plural form, 'millones,' especially when paired with 'de' and a plural noun.
⭐ Usage Tips
Use for Exaggeration
Using 'un millón' or 'millones' is a perfect way to dramatically exaggerate in casual speech, just like saying 'a million' in English.

Frequently Asked Questions
Do I need to use 'un' (one) before 'millón'?
Yes. Unlike 'mil' (thousand), 'millón' acts like a regular noun and must be preceded by 'un' (or 'dos', 'tres', etc.) when referring to the quantity. Always say 'un millón de personas', not just 'millón de personas'.
Why does 'millón' need 'de' afterward, but 'mil' (thousand) doesn't?
'Millón' (and 'billón', 'trillón', etc.) are treated as nouns in Spanish (the word 'million'). Nouns that describe an amount or container always need 'de' to connect to the things they contain: 'un millón de manzanas' (a million *of* apples). 'Mil' is treated more like a counting adjective, so it attaches directly: 'mil manzanas'.
