Prepositions after verbs

"Introduce to" or "introduce in"?

Use introduce to when presenting a person, idea, or subject to someone. Introduce in is not a standard verb-preposition pattern and usually refers to location or context.

Quick answer

Should I use introduce to or introduce in?

Use introduce to for presenting someone or making someone familiar with something: She introduced me to her colleagues. Introduce in is not normally used as a fixed combination after the verb introduce.

He introduced me to the manager.
The course introduces students to coding.
She introduced herself to the audience.

Choose the pattern by meaning

These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

1
introduce someone to + person

Presenting people to each other

Use to when connecting one person with another.

I'd like to introduce you to our new designer.
She introduced him to her parents.
2
introduce someone to + subject

Making someone familiar with a topic

Use to for first experiences with a subject, skill, or activity.

The workshop introduced us to digital animation.
This book introduces readers to local history.
3
introduce + object

Bringing in something new

Introduce can also take a direct object without a preposition.

The company plans to introduce a new policy.
They introduced stricter safety rules.

See the difference in context

The same subject can take different constructions because each sentence answers a different question.

Example

Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using in instead of to for people

Use to when presenting someone to another person.

✕ She introduced me in her friend. ✓ She introduced me to her friend.

Confusing introduce in with location phrases

In may describe when or where something was introduced, not the object of the verb.

✕ The teacher introduced students in robotics. ✓ The teacher introduced students to robotics.

Omitting to after introduce someone

Introduce normally needs to before the person or subject.

✕ He introduced me the team. ✓ He introduced me to the team.

Quick practice

Choose the expression that matches the intended meaning.

1. The guide introduced us ___ the city's history.
2. The software was introduced ___ several countries last year.
3. She introduced Daniel ___ the new project leader.
