If logophiles want to be lexicographers when they grow up, then lexicographers want to be etymologists. Etymology is the study of the history and origins of words, lexical genealogy, and etymologists are the practitioners of it. Lexicographers love the nerdy intricacies of a language, trading esoteric factoids like baseball cards, but etymologists master the nerdy intricacies of language, not just a language—language morphology, phonology, and history as a whole. The amount of information they know is almost superhuman.
