I grew up the progeny of a professor. My mom held a PhD in English and taught various forms of that field at the university level. She was a lover of literature and a guardian of grammar. In our home, words mattered and the improper use of syntactic structure could get you in as much trouble as the crude use of cursing.
Mom taught me that grammar is the glue that holds context and content together. When the glue is improperly applied, meaning can fall apart and crucial pieces of conversation can be lost. We talked often of using accurate articles, properly applied pronouns, and correct verb tense.
I didn’t care much for those language lessons as a child (particularly not as they were being drilled into me over summer vacation!), but, as the years have rolled on I’ve grown in my gratitude for the phonemic pedagogy of my parent.
