Here's a breakdown of the key elements:
* Word part: It's not a complete word on its own, but rather a piece that gets attached to another word.
* Added to the beginning: It always comes before the main part of the word.
* Change its meaning: It alters the original meaning of the word in a specific way.
Examples:
* "un-" in "unhappy" means "not"
* "pre-" in "preview" means "before"
* "multi-" in "multitasking" means "many"
Prefixes help us create new words and express more nuanced meanings.
