Can you make a noun that ends in plural by adding s Spanish?

It's not possible to make a noun plural in Spanish by simply adding "s". Spanish has a variety of ways to form plurals, and adding "s" is only one of them. Here's a breakdown:

Common ways to form plurals in Spanish:

* Adding -s: This is the most common method, but it only applies to nouns ending in a vowel or a consonant other than -n, -r, or -z. Examples:

* libro (book) -> libros (books)

* flor (flower) -> flores (flowers)

* Adding -es: This is used for nouns ending in -z, -x, -ch, or -j. Examples:

* cruz (cross) -> cruces (crosses)

* lápiz (pencil) -> lápices (pencils)

* Changing the ending to -es: This applies to nouns ending in -n, -r, or -s. Examples:

* mamá (mom) -> mamás (moms)

* papel (paper) -> papeles (papers)

* Keeping the singular form: Some nouns, especially those of foreign origin, remain singular in the plural. Examples:

* el autobús (the bus) -> los autobuses (the buses)

* el menú (the menu) -> los menús (the menus)

Important Note: The plural formation is determined by the gender and ending of the noun. Therefore, you cannot simply add "s" to any noun to make it plural in Spanish.
