The word it is one of the most common words in English. You see it in daily talk, school writing, signs, texts, books, and grammar lessons. Even though it looks simple, it does more than one job, so many learners want a clear explanation.
This article explains what it means, how it works as a pronoun, and why it also appears in sentences about weather, time, and general ideas. It also clears up the common confusion between it, it’s, and its, and shows how to use the word naturally in everyday English.
QUICK ANSWER
It meaning usually refers to the English pronoun it. Most often, it stands for a thing, animal, idea, or situation, and English also uses it as an empty subject in sentences about weather, time, distance, and general statements.
TL;DR
• It is usually a pronoun.
• It can be a subject or object.
• It often refers to a thing or idea.
• English uses dummy it for weather and time.
• It’s and its are different.
• Clear reference matters in writing.
What It Means in Plain English
In plain English, it is usually a word that stands in place of something else. That something may be a thing, an animal, an idea, a fact, or even a whole situation that was already mentioned or is already understood in context.
For example, in “Where is my phone? It is on the table,” the word it stands for my phone. In “It was a bad idea,” the word can point to a whole idea or situation instead of one physical object.
Part of Speech
In grammar, it is mainly a third-person singular pronoun. Collins and Oxford both describe it that way, and Cambridge shows it working as both a subject and an object.
Merriam-Webster also lists other meanings of it, such as a noun in expressions like it girl and an abbreviation in IT for information technology. But in normal grammar and learner use, the main meaning is the pronoun.
How It Works as a Subject and Object
It can be the subject of a sentence. That means it comes before the verb and names what the sentence is about. Example: “It smells terrible.”
It can also be the object of a verb or preposition. Example: “I found it” or “Put the letter in it.” Cambridge and Oxford both show this subject-object pattern clearly.
Dummy It: Weather, Time, Distance, and Dates
Sometimes it does not point to any specific thing at all. Cambridge calls this an empty or dummy it, and the British Council uses the same idea for sentences about time, date, and weather.
Examples include:
• It is raining.
• It is nearly one o’clock.
• It is my birthday.
• It is a long way from here to the station.
In these sentences, it is there because English clauses usually need a subject. The word helps complete the sentence, even though it does not refer to one clear object.
It with Clauses and Opinions
English often uses it before a clause or infinitive. Cambridge shows patterns like “It’s unlikely that she’ll arrive on time,” and the British Council shows patterns like “It’s great living here” and “It’s nice to meet you.”
This use helps speakers put the long or heavy part of the sentence later. That is why English often says “It is important to study” instead of starting with the longer phrase first.
Common Forms Related to It
The basic form is it. The possessive form is its, and the reflexive form is itself. Purdue’s pronoun-case page lists it / it / its, and standard grammar sources treat itself as the reflexive form.
A very common mistake is mixing up it’s and its. It’s is a contraction of it is or it has, while its shows possession. Example: “The dog wagged its tail” versus “It’s raining.”
How to Use It Clearly
When you use it, your reader or listener should know what it refers to. Purdue OWL warns that pronouns should refer clearly to a specific noun so the meaning does not become vague.
For example, “I put the book on the desk and it fell” can be unclear because it might mean the book or the desk. A better sentence is “I put the book on the desk, and the book fell off.”
Here is a simple guide:
| Context | Best Choice | Why |
|---|---|---|
| Referring to a thing already mentioned | it | Standard pronoun use |
| Showing possession | its | Possessive form |
| Saying “it is” or “it has” | it’s | Contraction |
| Referring back unclearly | repeat the noun | Avoid confusion |
The goal is not to avoid it, but to make sure it points clearly to the right word or idea.
Common Mistakes
One common mistake is using it’s when you need its. Remember: the apostrophe version is a contraction, not a possessive form.
Another mistake is using it with no clear referent. This can confuse the reader, especially in longer sentences with more than one possible noun.
A third mistake is thinking every it refers to a thing. In sentences like “It is cold” or “It is late,” the word is just filling the subject position.
