"Introduction to" is used when something is being presented as an explanation or beginning point. It's followed by a topic or subject. Examples:
* Introduction to Psychology: This refers to a course or book that introduces the basics of psychology.
* Introduction to the team: This signifies a brief presentation of the team members.
"Introduction of" is used when someone or something is being formally introduced. It's followed by the person or thing being introduced. Examples:
* Introduction of the new CEO: This refers to a formal presentation of the new CEO to the company.
* Introduction of the bill to the legislature: This means the formal process of submitting a bill for consideration.
Here's a simple way to remember:
* "To" is for subjects or topics.
* "Of" is for people or things.
If you're still unsure, try replacing the phrase with "a beginning about" or "a presentation of." If the sentence still makes sense, you've chosen the right preposition.
