Understanding how to use ‘for’ and ‘since’ correctly is crucial for mastering time expressions in English. Whether you’re learning English as a second language or looking to refine your grammar skills, grasping these concepts can significantly enhance your communication abilities.
Understanding ‘For’
‘For’ is a preposition used to refer to a period of time. It is often employed to indicate the duration of an action or event. When you use ‘for’, you’re talking about the entire duration an event has continued or will continue in the future.

For instance, in the sentence “I have lived here for five years,” the word ‘for’ tells us the duration of five years. You might use ‘for’ with different tenses such as present perfect, past simple, or future tense, depending on the context.
Examples of ‘For’ Usage
| Sentence | Explanation |
|---|---|
| I have been studying English for two hours. | The duration of studying is two hours, used with present perfect continuous tense. |
| They lived in London for a year. | The duration of living is one year, used with past simple tense. |
| He will travel for three weeks. | The duration of travel is three weeks, used with future tense. |
Understanding ‘Since’
‘Since’ is also a preposition, but it is used to refer to a specific point in time rather than a duration. It tells you when an action began. When using ‘since’, you often pair it with the present perfect tense to denote that the action started in the past and continues in the present.
For example, in “I have been living here since 2015,” ‘since’ marks the starting point of living in that location.
Examples of ‘Since’ Usage
| Sentence | Explanation |
|---|---|
| She has worked here since March. | The starting point of working is March, used with present perfect tense. |
| They have been friends since childhood. | The starting point of the friendship is childhood, occurs in the past continuing to the present. |
| I have not seen him since last year. | The starting point of not seeing is last year, continuing to the present. |
Common Mistakes and Tips
One common mistake is using ‘since’ when ‘for’ is necessary, and vice versa. A good tip is to ask yourself if you are talking about a period or a point in time.
- If it’s a duration, use ‘for’.
- If it’s a starting point, use ‘since’.
Additionally, consider practicing with exercises and quizzes to solidify your understanding. Using resources such as Cambridge English or the British Council can provide further guidance on this topic.
