The Double Had Had in a Sentence

Have you ever encountered the words “had had” in a sentence and thought you were seeing double?  Well, rest assured that your eyesight is all right and what you were seeing was a perfectly correct grammatical construction called the past perfect tense.

The Double Had Had in a Sentence

Perfect verb tense is used to show an action that is complete and finished, or perfected. This tense is expressed by adding one of the auxiliary verbs — have, has, or had — to the past participle form of the main verb.

Have + eaten

Has + finished

Had + loved

So what’s going on with the had had construction?

To understand the double had you have to remember that The past perfect is formed by using the past tense of have, which is HAD, and a past participle of the main verb, HAVE, which is also HAD. When we use “have” as a main verb we are using to mean  possess, own, hold for use, or contain.

So to be clear, have can be used as an auxiliary verb and as a main verb. Let’s think of this when forming the past perfect tense, when you want to indicate that you possessed, owned an action sometime in the past, but it is completed or perfected now.

You would use the past form of the auxiliary verb have which is HAD. And you would use the past participle of the main verb HAVE which is HAD.

  • Before the parent-teacher meeting, my teacher had (already) had many conferences with me due to my poor grades. (interrupted by an adverb).
  • I had had many opportunities to complete extra credit assignments before my final grade was posted. ( for emphasis) certainly
  • We had not had enough sleep the night before; therefore, we were very tired the morning of the test. (negative adverb not–show it also in the contracted form)

To conclude, please know that the use of ‘Had Had” is becoming less common and that although technically there is a difference between the past perfect tense and the simple past, semantically speaking, there is often little difference as long as the context is understood.

Common Irregular Verbs: Past Tense and Past Participle

For most verbs, in order to form the past tense, you simply add the suffix -ed to the main form of the verb called the infinitive. And to form the regular past participle which can be a verb form or an adjective, you usually keep the past tense form of the verb, that is the infinitive plus the suffix -ed. 

This means that the regular simple past and the participle forms of the verb are the same.

Like in this example: 

Love (main verb in the present)

loved (simple past formed by adding ed suffix) and

has/have loved ( past participle formed by adding the helping verb has/have and keeping the past tense form of the verb.

 

However, there are irregular verbs that do not follow the common structure of adding ed when making the past and past participle.
