Unlike a few of my colleague, I don't think teaching language and composition is beneath me. It is true that I am a scholar of literature, and not of language, but I find advanced level language courses to be very rewarding. Not being a linguist does not hold me back. Most of the students want to improve their level of Spanish language, and this occurs both in literature classes and in those devoted to the language itself. Literature classes are also language classes, in fact.
This semester I have two advanced language courses, and it frees my literature mind entirely for my own research.
