[Grammar] I did say / I said

[Lemon~Tree]

Hi,

1) I did say you all I knew.
2) I said you all I knew.

Could you explain what is the purpose of the helping verb did in first sentence? What is the meaning difference between both sentences?

 

[Skrej]

Where did you find these sentences? Neither one of them is correct as written, so I can't answer your question.

 

[Barb_D]

Perhaps you mean:
I did tell you everything I knew (about it).
I told you everything I knew (about it).

The second is standard. The first is insisting. Perhaps something like this:

A: [after a long conversation] Well, that's about it.
B: You said you'd tell me everything you knew about it.
A: I did tell you everything about it!

In affirmative sentences, we sometimes use do, does, did, followed by the bare infinitive of the main verb to express emphasis:

1. I do love my job. (Present Simple)
2. He does love his job. (Present Simple, third person singular)
3. I did love my job. (Past Simple)

Note: We use "say" and "tell" differently but that's another matter altogether.
