💡 Grammar Points
Stays the Same in Plural
Unlike other numbers, 'mil' doesn't change when you put another number before it. It's 'dos mil' (2,000), 'cinco mil' (5,000), 'cien mil' (100,000), etc. The word 'mil' itself stays the same.
No 'Un' Needed
When you mean exactly 1,000, you just say 'mil', not 'un mil'. For example, 'Tengo mil libros' (I have a thousand books).
❌ Common Pitfalls
Saying 'un mil'
Mistake: "Compré un mil cosas en el mercado."
Correction: Compré mil cosas en el mercado. You only need to say 'mil' for 'one thousand'. The 'un' is not necessary and sounds unnatural.

'Mil' is essential for saying years, like 'mil novecientos noventa y nueve' for 1999 or 'dos mil veinticuatro' for 2024.

⭐ Usage Tips
