Another one we hear as often as the misuse of "seen" is "come" as a past tense. For instance, instead of, "yesterday, I came here", we will often hear ,"yesterday I come here". And in the Ebonics dialect, mentioned above, we hear, "yesterday he come up in here". "All up in it" is an often used phrase that makes us laugh at school. We correct the students, but like all other grammatical/dialectical (is this a word?) errors, they continue to use them.
