Has vs Had: Understanding the Difference

Present Perfect Tense with Has

In English grammar, the present perfect tense is used to describe an action that happened at an unspecified time before now, or an action that started in the past and continues up to the present moment.

To form the present perfect tense, we use the auxiliary verb “has” with the past participle of the main verb. For example, “He has eaten breakfast already” or “She has finished her work for the day”.

It’s important to note that “has” is used with singular subjects (he, she, it) while “have” is used with plural subjects (they, we, you). Additionally, the present perfect tense is often used with time expressions such as “just”, “already”, and “yet”. For example, “I have just finished my homework” or “We haven’t eaten dinner yet”.

Overall, understanding how to use “has” in the present perfect tense can greatly improve your English speaking and writing skills.

Past Perfect Tense with Had

The past perfect tense is used to describe an action that was completed before another past action. It is formed by using the auxiliary verb “had” with the past participle of the main verb. For example, “She had already eaten breakfast before he arrived” or “I had finished my work before I went to bed”.

It’s important to note that the past perfect tense is often used with time expressions such as “before”, “after”, and “when”. For example, “She had already left before I arrived” or “I had finished my presentation when the power went out”.

Using “had” in the past perfect tense can help clarify the sequence of events in a story or conversation, and can make your writing more coherent and easy to follow.

Examples of Has and Had in Sentences

To better understand the usage of “has” and “had”, it’s helpful to see them in action in sentences. Here are some examples:

  • She has lived in Paris for five years. (present perfect tense)
  • They have finished their project ahead of schedule. (present perfect tense)
  • He has never visited Japan before. (present perfect tense)
  • I had already seen that movie before we watched it together. (past perfect tense)
  • She had completed her degree by the time she turned 25. (past perfect tense)
  • They had been married for ten years before they had their first child. (past perfect tense)

In each of these examples, “has” and “had” are used to indicate a completed action or state, either in the present perfect tense or the past perfect tense.

Common Mistakes and Tips for Proper Usage of Has and Had

One common mistake when using “has” and “had” is confusing the present perfect tense with the past perfect tense. Remember that the present perfect tense uses “has” (singular subjects) or “have” (plural subjects) with the past participle, while the past perfect tense uses “had” with the past participle.

Another mistake is using “has” or “had” with the wrong tense. For example, saying “He has went to the store” instead of “He has gone to the store” is incorrect. Make sure to use the correct past participle form of the verb.

To avoid these mistakes, it’s helpful to practice using “has” and “had” in context, and to pay attention to the tenses of the verbs you are using. Additionally, using time expressions like “just”, “already”, and “yet” can help clarify whether you should use the present perfect tense or the past perfect tense.

Overall, understanding the proper usage of “has” and “had” can greatly improve your writing and speaking skills in English.
