Algumas vs Alguns

What’s the difference between algumas and alguns? Are they interchangeable?
Could the sentence ‘Eu como algumas maçãs.’ also be written as 'Eu como alguns maçãs?

The difference is gender: alguns is the masculine plural form of algum (some), and algumas is the feminine plural form. Maçã, being a feminine word, requires you to use algumas. Hence the correct sentence is “Eu como algumas maçãs.”


Thanks! That makes sense. I guess I was confused because when I looked in Linguee, it has all 4 words as pronouns, but never states whether they are masculine or feminine, which it usually does for other words.
