Time Clauses in English: Before, After, When – Rules and Examples

Understanding and using time clauses with before, after, when can greatly enhance your English speaking and writing skills. These clauses help indicate the timing of an event relative to another and are essential for constructing meaningful and precise sentences.

What are Time Clauses?

Time clauses are dependent clauses used to relate to the timing of the action described in the main clause. Usually introduced by conjunctions such as ‘before’, ‘after’, and ‘when’, these clauses provide temporal context. For example, in the sentence, “I will call you before I leave,” the clause ‘before I leave’ specifies when the action in the main clause will occur.

Using ‘Before’ in Time Clauses

The conjunction ‘before’ is used to specify an action that occurs prior to another action. Typically, the action described in the time clause has a sense of preceding the other action in the main clause. Consider this structure: ‘[Main Clause] + before + [Time Clause]’. A useful example would be, “I always have my coffee before I start work.” Moreover, you can reverse the order: ‘Before [Time Clause], [Main Clause]’. Here’s how you can practice:

• Complete this sentence: “You need to wash your hands before you ____.”
• Discuss: Why is it important to perform certain actions before others in a daily routine?

Using ‘After’ in Time Clauses

‘After’ is used to denote an action that follows another event. This is straightforward and usually forms sentences such as ‘[Main Clause] + after + [Time Clause]’. For instance, “She called me right after she finished her meeting.” You can also write it as ‘After [Time Clause], [Main Clause]’ like “After she finished her meeting, she called me.”

Practice this by finishing this: “After I graduate, I plan to ____.” Consider situations where you need to plan one event after finalizing another.

Using ‘When’ in Time Clauses

The conjunction ‘when’ is versatile and can describe simultaneous actions or sequences. It is used when two actions are happening at the same time or one immediately follows the other. For example, “When the sun rises, the birds start singing.” Notice how the occurrence of two events is linked. Alternatively, ‘When [Time Clause], [Main Clause]’ like “When you arrive, please call me.”

Try forming your own sentence: “When I ____ , I feel most ____.” Reflect on personal experiences or routines.

Common Mistakes and Tips

Here are some tips and common mistakes to avoid when using time clauses:

• Do not use the future tense after time conjunctions like before, after, or when. Instead of saying, “I will call you when I will arrive”, say “I will call you when I arrive.”
• Ensure the sequence of events is logical. Think about whether the actions need to happen in a specific order.
• Practice writing sentences using different constructions to gain fluency in using time clauses.
