Introduction To or Introduction Of: Which One Is Correct?(2026)

Choosing between “introduction to” and “introduction of” can be confusing because both expressions are grammatically correct. The difference depends on what you are introducing and what role the phrase plays in the sentence. Knowing this distinction can make your English sound more natural and precise.

In general, “introduction to” is used when someone is being introduced to a subject, topic, skill, place, or experience. “Introduction of” is usually used when a person, product, idea, system, or concept is formally presented or brought into use. Understanding this simple difference will help you choose the right expression in academic, professional, and everyday English.

Quick Answer

Use “introduction to” when talking about becoming familiar with something.

• An introduction to English grammar
• An introduction to photography
• An introduction to the topic

Use “introduction of” when something or someone is formally presented, launched, or brought into a situation.

• The introduction of a new policy
• The introduction of a new product
• The introduction of the speaker

Easy rule:
Introduction to = becoming familiar with something
Introduction of = presenting or bringing something in

Why Do People Confuse “Introduction To” and “Introduction Of”?

The confusion happens because both phrases contain the noun introduction, and both can refer to presenting something.

However, the preposition changes the relationship between the words.

Consider these examples:

This course provides an introduction to biology.

Here, biology is the subject that learners are becoming familiar with.

Now compare:

The introduction of a new biology course was announced yesterday.

Here, the course itself is something that has been newly introduced or launched.

The key question is:

Are you becoming familiar with something, or is something being presented or introduced?

• The workshop provides an introduction to digital marketing.
