Sic

Sic is text indicating the writer is aware of a spelling or grammar error and is intentional, usually due to being quoted. Sic is often italicized and placed within square brackets, like [sic].

For example, "Joe's message said he ejoys [sic] sending e-mail" indicates "ejoys" is intentionally misspelled because it is how Joe spelled it.
