💡 Grammar Points
One Form for All
The word 'ochenta' never changes. Whether you are talking about eighty boys (niños) or eighty girls (niñas), the word stays exactly the same.
Adding Numbers
To say numbers like 81 or 85, you just add 'y' (and) and the single digit: 'ochenta y uno', 'ochenta y cinco'.
❌ Common Pitfalls
The 'Y' Rule
Mistake: "Writing 'ochentayuno' as one word."
Correction: Always write it as three separate words: 'ochenta y uno'. Only numbers 16-29 are usually combined into one word.
