English grammar originated in the late 16th century with the publication of Pamphlet for Grammar. Written by William Bullokar, the pamphlet bases English grammar on those rules and guidelines that were found, and based, in Latin. There was a more modern approach introduced in the 19th century.
Grammar is also ever-changing based on popular usage and changes in the form of the language. Additionally, grammar rules that once were extremely strict and not to be strayed from have become loosened and open for interpretation. In school, the youth of America are taught the hard and fast rules that are not to be broken. However, once that youth grows up a little bit, they realize there is a little bit more leniency when it comes to grammar, but as long as they are in school, they will be graded on the black and white grammar rules.
So how much do you remember about grammar? Honestly, there's a lot of stuff to remember, and it can all get jumbled in your brain when you're also expected to remember the capitals of all the states, the preamble to the Constitution and the entire breakdown of the solar system. Fix these sentences and we'll rate your grammar knowledge on a scale of 1-10!
