Dummy/Preparatory "it"

The dummy or preparatory 'it' acts as a placeholder subject in English sentences where there is no real actor or to introduce a later subject.

01 / Overview

In English, every sentence usually needs a subject. We use it as a 'dummy' subject when we talk about time, weather, or distance because there is no person or thing doing the action. We also use it as a 'preparatory' subject to introduce an idea before a longer phrase, such as an infinitive.

02 / Form

It + is/was + adjective/noun/verb-ing

The dummy it always takes a singular verb, usually the verb to be. It does not refer to a specific noun mentioned before.

03 / Examples

04 / Common mistakes

  • Is cold today.

    It is cold today.

    English sentences require a subject. You cannot leave the subject position empty when talking about the weather.

  • To learn English is important.

    It is important to learn English.

    While the first version is grammatically possible, using 'it' as a preparatory subject is much more natural in spoken English.

05 / It vs. There

Do not confuse 'it' with 'there'. Use 'it' to describe a state or condition, and 'there' to point out the presence of an object.

UsageExample
Use 'It' for weather, time, and distance.It is sunny.
Use 'There' to say something exists.There is a sun on the flag.
