I'm using the textbook Fuentes: Conversación y gramática, and in it it states:
"To talk about indefinite quantity in affirmitive sentences and questions, use the following adjectives and pronouns."
The book then goes on to list the following adjectives:
If the word alguno can be pluralized, why -- or how -- would you use the word algún to represent an indefinite quantity of objects? It looks like a singular adjective to me. The book only gives examples of algunos and algunas.
Is it similar to the way that the words less and fewer are used in English?
