Understanding the Present Perfect Tense

The present perfect tense is a unique verb form that connects past actions or states with the present moment. It is typically formed by combining the auxiliary verb have/has with the past participle of the main verb. For example:

• She has lived here for five years.
• They have finished their homework.

This tense is particularly useful when the exact time of the action is not specified or when the action has relevance to the current situation. The present perfect often pairs with time expressions such as for and since to indicate duration, which we will examine in detail.

Difference Between ‘For’ and ‘Since’ in Present Perfect

Both for and since are used to talk about how long something has lasted, but they are applied differently depending on whether you are indicating a period of time or a specific starting point.

Using ‘For’

For is used to describe the length or duration of an action or state. It answers the question, “How long?” The duration can be in seconds, minutes, hours, days, months, years, etc. Examples include:

• I have lived in this city for ten years.
• She has been studying English for three months.
• They have worked together for over a decade.

Using ‘Since’

Since is used to indicate the specific point in time when an action or state began and continues up to the present. It answers the question, “Since when?” Examples include:

• I have lived here since 2015.
• He has worked at the company since January.
• We have been friends since childhood.

How to Form the Present Perfect with For and Since

Understanding the correct formation is essential to using this tense effectively. The formula for present perfect with for and since is:

Subject + have/has + past participle + for/since + time expression

Note the use of have with plural subjects and has with singular third-person subjects.

Examples:

• She has worked here for five years.
• They have known each other since 2010.

Common Mistakes to Avoid When Using Present Perfect with For and Since

Many English learners struggle with the present perfect tense, particularly with the correct use of for and since. Below are some frequent errors and tips on how to avoid them:

1. Using ‘Since’ with a Duration Instead of a Starting Point

• Incorrect: I have lived here since five years.
• Correct: I have lived here for five years.

Since must be followed by a specific point in time, such as a year, date, or event.

2. Using ‘For’ with a Specific Starting Point

• Incorrect: He has worked here for 2010.
• Correct: He has worked here since 2010.

3. Omitting the Present Perfect Tense

• Incorrect: I live here for five years.
• Correct: I have lived here for five years.

Remember, the present perfect is necessary to express actions or states that began in the past and continue into the present.
