💡 Grammar Points
It Always Stays the Same
Unlike many Spanish adjectives, 'ocho' never changes. It's always 'ocho libros' (eight books) and 'ocho mesas' (eight tables). It doesn't become plural.
❌ Common Pitfalls
Adding an 's'
Mistake: "Tengo ochos gatos."
Correction: Tengo ocho gatos. (I have eight cats.) The numbers you count with don't get an '-s' to become plural.
⭐ Usage Tips
Telling Time
To say 'at eight o'clock,' use 'a las ocho.' The 'las' is there because you're really saying 'at the eight hours' (a las ocho horas).

The noun ocho refers to the number or figure eight itself, often visualized by a figure-eight shape.
📝 In Action

A1My lucky number is eight.

A2She got an eight on the math test.

A1Draw an eight on the board.
💡 Grammar Points
Always Masculine ('el')
When you talk about the number 'eight' as a concept or a thing, it's treated as masculine. That's why you say 'el ocho'.

Frequently Asked Questions
Why is it 'ocho años' and not 'ochos años' for 'eight years'? Don't adjectives have to match in number?
That's a great question! Cardinal numbers (like uno, dos, tres...ocho) are a special exception. When they are used to count things, they don't change to become plural. It's always 'ocho gatos' (eight cats), never 'ochos gatos'.
When do I use 'octavo' instead of 'ocho'?
Use 'ocho' when you are counting how many of something there are (e.g., 'ocho libros' - eight books). Use 'octavo' to talk about the order or position of something (e.g., 'el octavo piso' - the eighth floor).
