First Conditional: Should in Result Clause

This structure links a possible future event with a recommendation. The 'if' part describes a situation that might actually happen. It is not a dream or an impossible fantasy. It is a real possibility. The second part—the result clause—is where you give your advice. Instead of saying what *will* happen, you say what *should* happen. It is like a grammar traffic light. The 'if' clause is the green light. The should clause is the direction you suggest taking. You use the Present Simple for the condition. You use should plus the base verb for the advice. It is simple, clean, and very effective for daily talk. Even native speakers rely on this to avoid sounding too bossy.

1. 1Creating this sentence is like building with Lego blocks. You need two main parts. Follow these steps to get it right every time:
2. 2Start with If to introduce the condition.
3. 3Add the subject and a verb in the Present Simple tense.
4. 4Place a comma to separate your thoughts (if writing).
5. 5Add the subject for the result clause.
6. 6Use the modal verb should followed by the base verb.
7. 7Example: If (1) + you + go (2) + , (3) + you (4) + should + wear (5) a coat.
8. 8Remember, the base verb never has 'to' or an '-ing' ending. It is just the pure verb. It stays the same even if the subject is he, she, or it. No extra 's' is needed here!

You will find this pattern everywhere in the real world. Imagine you are ordering food at a new restaurant. Your friend is undecided. You say, "If you like spicy food, you should try the red curry." It is the perfect suggestion. Or think about asking for directions. A local might tell you, "If you see the big clock tower, you should turn left." It is helpful and clear. In job interviews, this grammar is a lifesaver. You might say, "If the company grows, we should expand the marketing team." It shows you are thinking ahead. Use it when you want to be helpful but not demanding. Use it when the future is uncertain but you have a good idea. It works for health tips, travel advice, and office teamwork.

Don't use this when you are 100% sure of a result. If you drop an egg, it *will* break. You don't say it *should* break (unless you are testing gravity!). Avoid this pattern for past regrets too. That requires a different conditional entirely. Also, don't use it for impossible fantasies. If you were a bird, you wouldn't use this structure. This is for real-world, possible scenarios only. If the condition is 0% likely, stay away from the First Conditional. Finally, don't use it if you want to give a direct command. If a building is on fire, don't say "You should leave." Just say "Leave!" or "You must leave!"

One big mistake is using will and should together. You cannot say "If it rains, you will should stay." Pick one! Another classic error is putting will in the 'if' clause. "If it will rain" is a no-go zone. Keep it simple: "If it rains." Many people also forget that should is a modal verb. This means you never say "should to go" or "should going." It is always just should go. Yes, even native speakers mess this up when they are tired! Another trap is the third-person 's'. People often say "He should goes." Nope! It is always "He should go." Think of should as a shield that protects the verb from any changes.

How does this differ from the standard First Conditional? The standard version uses will. If it rains, I will stay home. This is a statement of fact or a firm promise. It is 100% going to happen in your mind. Using should changes the vibe. If it rains, you should stay home. Now, it is a piece of advice. You are giving the other person a choice. It is much softer. What about might? If it rains, I might stay home. This is about possibility. You aren't sure yet. So: will is a promise, might is a maybe, and should is a suggestion. Choosing the right one shows you really understand English nuances.
