Has, have and Had generally pose confusions for non-native English speakers. They are auxiliary(helping) verbs used to form sentences in the Perfect Tense, as well as stand-alone verbs to form the Simple Present tense.
To understand about whether using them doubly, like had had, have had and has had, is correct, we will have to take a look at the present perfect and past perfect tenses.
The perfect tense always uses has / have (present) / had (past) + past participle. Click here for more information on past participles.
Here's are a couple of examples of Perfect Tense:
Eg.: Mila has done her homework. (Present Perfect)
Eg.: Mike and Molly have eaten their dinner. (Present Perfect)
Eg.: Philip had gone to the market yesterday. (Past Perfect)
We use has/have and had in Simple Tense, minus the past participle:
Eg.: I have a pet dog. (Simple Present)
Eg.: She has chicken pox, so don't go near her. (Simple Present)
Eg.: I had a pretty blue frock when I was small. (Simple Past)
When we use them to form Perfect tense sentences, for example Present Perfect tense, we can use 1 have/has + 1 had in place of the past participle, as per the rule.
The past participle form of have and has is had.
I
|
have
|
had
|
a
|
lot
|
of
|
homework
|
this
|
week.
|
Present Perfect
|
PP of have
|
He
|
has
|
had
|
a
|
lot
|
to
|
drink
|
tonight.
|
|
Present Perfect
|
PP of has
|
In the same way we can use had had to form Past Perfect:
I
|
had
|
had
|
a
|
severe
|
cold
|
last
|
month.
|
|
Past Perfect
|
PP of have
|
So there you go! As long as you have a Past Participle after have/has/had, you are talking in Perfect tense. If using these three verbs alone with an object, you are in the Simple Tense.
Can I use HAD HAD, HAVE HAD, and HAS HAD??
