I is

[diplomacy]

I have seen

I is.......

in which case we use it?


i just know I am

[2utopian]

I cannot think of a single instance in which "I is..." is used.
The only time that it would be used is in slang. It shows an uneducated person.

[Ouisch]

In AmE, "I is" is usually used when quoting or imitating Black English or Ebonics. A lot of literature written during the Civil War era would adopt the dialect used by slaves at the time, which included "I is" instead of the more correct "I am."

I would daresay that unless you are of African heritage, or are a rapper using the phrase in your lyrics, saying "I is" would brand you as a racist and folks would think that you were mocking the Black population.

It could also show a well-educated person who chooses to speak non-standard English for his own purposes.

I would say ' I is the ninth letter of the English alphabet' joking of course!
