“I want to pause here to digress on the seemingly underwhelming concepts of coordination and subordination. I will ask you to stifle your yawn as I acknowledge that they are easy to dismiss–ancient, faintly risible, uttered once long ago by acolytes of sentence diagramming in the era of chalk dust. They smack of grammar for grammar’s sake, and almost nobody cares about that. Teachers instead seek mostly to simply make sure the sentences work and dispense with the parsing of parts. It is so much simpler to tell kids to go with ‘sounds right’ (an idea that inherently discriminates against those for whom the sounds of language are not happily ingrained by luck or privilege) or to make the odd episodic correction and not worry about the principle at work.
But coordination and subordination are in fact deeply powerful principles worth mastering. They describe the ways that ideas are connected, the nuances that yoke disparate thoughts together. It is the connections as much as the ideas that make meaning. To master conjunctions is to be able to express that two ideas are connected but that one is more important than the other, that one is dependent on the other, that one is contingent on the other, that the two ideas exist in contrast or conflict. Mastering that skill is immensely important not just to writing but to reading. Students who struggle with complex text can usually understand the words and clauses of a sentence; it is the piecing together of the interrelationships among them that most often poses the problem. They understand the first half of a sentence but miss the cue that questions its veracity in the second half. And so without mastery of the syntax of the relationships–which is what coordination and subordination are–the sentence devolves–for weak readers–into meaninglessness.”
