So many people ask why children aren't taught grammar and punctuation at school. Many of our teachers today have been produced by the same education system that they now teach in, so the simple answer is that they cant teach grammar and punctuation because they have never learnt it themselves. There have in recent years been meaningful improvements in the level of functional literacy among school leavers, but at the other end of the spectrum universities are complaining about the poor writing skills of undergraduates. These complaints are not raised because of a failure by students to correctly use the subjective clause or to err by leaving participles dangling, but far more fundamental failures in, for example, the use of apostrophes and capitalization. Most commentators describe errors of grammar and punctuation as irritating. To become irritated one must first recognize the error, and the majority of people, including many teachers, do not have a sufficient grasp of the rules to realize that a mistake has been made.
