Question

when we can use'had had'.

Answer 1

It is correct, though it too might seem a bit awkward. To understand “had had,” we need to take a look at the present perfect and past perfect tenses. Take this sentence: “I have had too many chocolates today.” That sentence is in the present perfect tense.

Answer 2

Answer:

Using words such as had had and do do can be used to prove something or applying some sort of pressure over the sentence that it is true. For examples,

1) Radha: You do not workout in the gym.

Raju: I do do workout. You're bugging.

OR

2) Ram: She had completed completed her work.

Suresh: No she hadn't had completed it.

Hope you understood. Took me efforts to write it. Mark it as the brainliest to make my efforts worth it :3
