* Liten: This is the most common and general word for "little," referring to size. It's used for both things and people.
* Lill-: This is a prefix often used before nouns to mean "little." For example, "lillasyster" means "little sister" and "lillebror" means "little brother."
* Små: This word means "small" and is the plural form of "liten." You'd use it for multiple little things.
* Lite: This word means "a little" or "some," and refers to quantity rather than size. For example, "lite vatten" means "a little water."
So, the best translation depends on what you're trying to describe.
