If we go... If you see...

This lesson focuses on conditional sentences that begin with if + present simple and the common ways to complete them. You will learn the first conditional (real future possibilities) and how to use an imperative or modal verbs after an if-clause to give instructions, requests, offers, or suggestions.

• If + present simple → will / can / may + base verb (first conditional).
• If + present simple → imperative (for instructions or quick requests).
• Useful in business situations: offers, requests, warnings, and plans.

The most important rule is to use the present simple in the if-clause. The main clause can be a future modal form or an imperative depending on the meaning.

• If-clause: use present simple (If we go, If you see).
• Main clause for future outcomes: use will / can / may + base verb (We'll confirm; You can ask).
• Main clause for instructions/requests: use the base verb (imperative) without subject (Tell him; Bring the file).

If the if-clause comes first, place a comma after it: If you see any problems, let me know.

Many learners make predictable errors when using if-clauses. Watch out for:

• Using will in the if-clause (Incorrect: If we will go...).
• Mixing unrelated tenses (e.g., If we went ... + will in formal real conditions).
• Using the wrong verb form after modals (should use base verb after can/may/will).
• Forgetting to use the base verb for imperatives (wrong: If you see him, you tell him).

Focus on structure: If + present simple, then choose the correct main clause form.
