 There are concerns for the growing infiltration of informal language use and incorrect word use into academic or formal situations, such as the usage of casual words like "guy" or the choice of the word "preclude" in place of "precede" in academic papers by students.There are also issues with spellings and grammar occurring at a higher frequency among students' academic works as noted by educators, with the use of abbreviations such as "u" for "you" and "2" for "to" being the most common.Linguists and professors like Eleanor Johnson suspect that widespread mistakes in writing are strongly connected to Internet usage, where educators have similarly reported new kinds of spelling and grammar mistakes in student works.
