First Conditional: Be Going To in Result Clause

This structure links a possible future condition to a plan. The if clause sets the scene for the action. The result clause uses be going to to show intent. It suggests that the decision is already made. You aren't just guessing about the future result. You are stating what your planned response is. It feels more certain than using the word will. Imagine you are at a restaurant with friends. If the waiter brings the wrong food, you have a plan. You are going to send it back immediately. The condition is the wrong food arriving. Your planned intention is the act of sending it back. It connects a possible trigger to a pre-set reaction. This grammar helps you express your personal boundaries and goals.

1. 1Creating this structure is like following a simple recipe. You need two distinct parts for a complete sentence.
2. 2Start with the if clause using if + present simple.
3. 3Add a comma if the if clause comes first.
4. 4Use the subject + am/is/are + going to + base verb.
5. 5You can also reverse the order of the clauses.
6. 6If you reverse them, do not use a comma.
7. 7For example: If I win, I am going to buy a car.
8. 8Or: I am going to buy a car if I win.
9. 9Both sentences mean the exact same thing to the listener.

Use this when you have a firm intention or plan. It works great for professional settings like job interviews. If they offer you the job, you're going to accept it. It shows you have thought about your future steps. Use it when discussing travel plans with your family. If the tickets are cheap, we're going to visit Rome. It also works for logical consequences based on evidence. If you don't study, you're going to fail the exam. This isn't just a guess; it is a logical plan. It is very common when talking about health or fitness. If I feel tired, I am going to take a nap. It sounds much more personal than using will in these cases. Think of it like a grammar traffic light turning green. The condition happens, and your plan moves forward immediately.

Do not use this for instant, snap decisions. If the phone rings, you say I will answer it. You don't say I am going to answer it usually. Instant reactions almost always require the use of will. Avoid this pattern for general scientific truths or facts. If you heat ice, it melts (not is going to melt). This structure is specifically for human intentions and planned results. Also, do not use it if you are very unsure. If you are just guessing, might or will is better. Using be going to implies you have a clear path. Don't use it if the result is a total surprise. It should feel like a logical or intended next step.

Many people put will inside the if clause. This is a very common trap for many learners. Never say If it will rain, I am going to stay. Always use the present simple after the word if. Another mistake is forgetting the am, is, or are. If I see him, I going to say hello is wrong. You must include the auxiliary verb for it to work. Some people also forget the to after the word going. Always remember the full phrase be going to plus verb. Even native speakers mess this up when they speak fast. They might say gonna, which is fine for casual talk. But in writing, keep the full form for clarity. Think of these mistakes like a loose shoelace. You can still walk, but you might trip eventually.

How does this differ from the standard will version? Will is often for predictions or promises made now. Be going to is for plans made before speaking. Compare: If it rains, I will stay (a simple prediction). Compare: If it rains, I am going to stay (my plan). The second one sounds like you already decided your reaction. It feels more deliberate and less like a random guess. It is also different from the second conditional. The second conditional is for imaginary or impossible situations. This pattern is for things that might actually happen soon. It is grounded in reality and your actual future life. Use it when you are talking about real-world possibilities.
