How can you use some in a sentence as pronoun?

Here are a few examples of "some" used as a pronoun in sentences:

* "Some" of the students were late for class. (Here, "some" refers to an unspecified number of students.)

* "Some" say that the world is ending, but I'm not buying it. (Here, "some" refers to an unspecified group of people.)

* "Some" were happy, while others were sad about the news. (Again, "some" refers to an unspecified group, contrasting with another unspecified group.)

Remember that "some" as a pronoun can often be used to avoid being specific or to refer to an undefined group or amount.
