it
"It" is one of the most frequently used words in English. It is primarily a pronoun, but it works in several different ways depending on the sentence. Here are the most important uses you will encounter every day.
In English, when you talk about the weather, the time, the date, or general conditions around you, you must use 'it' as the subject — even though 'it' does not refer to any specific thing. This is called a 'dummy subject'. There is no real meaning behind 'it' here; it just fills the subject position that English requires.

Sometimes 'it' is used to introduce a whole idea or situation, especially with phrases like 'it is important that…', 'it seems that…', or 'it is easy to…'. Again, 'it' is a dummy subject — the real subject is the idea that comes after. This structure makes sentences feel more natural and balanced in English.

You can use 'it' to refer to a general situation, experience, or feeling that is already understood from context — not a specific object. For example, if you are having a hard day, you might say 'It is tough.' The 'it' refers to the whole situation you are both aware of.
