Philology- love for words.

Being a big fan of Tolkien's writings, I always like the new words that writers coin up. Rowling's writings also happen to be in that category. The etymological study of a word upto its root words is very interesting. Knowing older languages like Sanskrit and Latin are quiet beneficial. I wish at times I were doing some research on philology rather than computer science. But any ways the opportunity to challenge the mind, thats what matters most to me.
