If

If is a word we use when something depends on another thing. It’s used when talking about a condition or something that might happen. For example, “If it rains, we will stay home.” It can also express doubt or possibility, like “I don’t know if he’s coming.” Sometimes, it shows a choice between two results, like “If you work hard, you will succeed in life; if not, you won’t”. We use “if” every day to talk about choices, plans, or results that are not certain yet.
