Common Questions About 78 in Spanish

Why is 'y' used in setenta y ocho but not in dieciocho?

Does setenta y ocho change with masculine or feminine nouns?
Unlike hundreds (doscientos/doscientas), the number setenta y ocho stays the same regardless of the noun's gender. You would say 'setenta y ocho sillas' and 'setenta y ocho libros' without any modification.
How do you write 78 in words on a Spanish check or legal document?
On formal documents, you write 'setenta y ocho' in lowercase letters, typically followed by the currency in words. Some legal templates capitalize the first letter or place the amount in parentheses for clarity, such as '(Setenta y ocho pesos).'
