Definition of Have and Had
The words “have” and “had” are auxiliary verbs, also known as helping verbs, that are used to form perfect tenses in English. They do not carry the main meaning of the sentence but rather assist the main verb in expressing time and completion of an action.
Understanding their function is essential for using English grammar correctly. “Have” is used primarily in the present perfect and future perfect tenses, while “had” is used in the past perfect tense.
They indicate that an action has been completed at some point before a reference point in time.
Have: Functions as an auxiliary verb in the present perfect and future perfect tenses. It indicates that an action was completed at some point before the present or will be completed before a specific time in the future. It is also used as a main verb to indicate possession. For example, “I have a car.”
Had: Is the past tense form of “have” and is used as an auxiliary verb in the past perfect tense. It indicates that an action was completed before another action in the past. It can also be used as a main verb to indicate past possession. For example, “I had a bicycle when I was young.”
Structural Breakdown
The structural usage of “have” and “had” is determined by the tense being formed. Each tense has a specific structure that must be followed to ensure grammatical correctness.
Understanding these structures will help you to form correct sentences and avoid common errors.
Present Perfect: Subject + have/has + past participle of the main verb. For example, “I have eaten dinner.”
Past Perfect: Subject + had + past participle of the main verb. For example, “I had eaten dinner before he arrived.”
Future Perfect: Subject + will have + past participle of the main verb. For example, “I will have eaten dinner by the time he arrives.”
The auxiliary verb agrees with the subject in number and person. For instance, “I have,” “he has,” “they have.” In the past perfect, “had” remains the same regardless of the subject.
The main verb is always in the past participle form, which typically ends in “-ed” for regular verbs but can vary for irregular verbs (e.g., “gone,” “eaten,” “seen”).
Types and Categories
Understanding the different tenses in which “have” and “had” are used is essential for mastering their application. Each tense conveys a different relationship between the action and the time frame.
Present Perfect
The present perfect tense connects a past action to the present. It is used to express actions that started in the past and continue to the present, actions completed at an unspecified time in the past, or actions that have a result or relevance in the present.
This tense emphasizes the connection between the past and the present.
Structure: Subject + have/has + past participle
Example: “I have lived here for five years.”
Past Perfect
The past perfect tense describes an action completed before another action in the past. It is used to clarify the order of past events, indicating which action occurred first.
This tense helps to establish a clear sequence of events in the past. It’s often used with time expressions such as “before,” “after,” or “by the time.”
Structure: Subject + had + past participle
Example: “I had finished my work before he arrived.”

The perfect continuous tenses combine the perfect and continuous aspects, emphasizing the duration of an action leading up to a specific time. These tenses provide a more nuanced understanding of the timeline of events.
