It is often used to create a feminine form of a noun, or to indicate something smaller, younger, or less important than the original word.
Examples:
* Stella: "little star" (from "stella" meaning "star")
* Marcella: feminine form of "Marcel"
* Camellia: a type of small flower
* Isabella: feminine form of "Isabel"
* Cinderella: "little ash girl" (from "cinder" meaning "ash")
It's worth noting that the suffix "-ella" is primarily used in Latin-derived languages, such as Italian, Spanish, and Portuguese.
