Some

/sʌm/ (stressed) or /səm/ (unstressed) determiner, pronoun, adverb

Some is used to talk about an unknown or not exact amount of something. It can also mean “a certain” when you don’t want to say exactly who or what.

From Old English *sum* meaning “one, a certain one, some,” related to German *sum* and Sanskrit *sam* meaning “together.” It originally had a stronger sense of “a particular one” than today.
