Indo-European Etymology

Etymology, defined as a branch of linguistics, investigates word histories. Latin etymologia was taken from Ancient Greek etumologíā. It consists of Greek étumo- (“true”) and -logíā (“study, investigation”) hence the literal meaning was “study of the truth [in words].” As a concrete noun, an etymology is the account of a specific word’s history. “History” by definition, primarily refers to the linguistic history of the word: When did it first appear in the language? Did it develop from previous words, or was it borrowed from another language? How did it arise, and by which phonological or morphological operations? How did it change in the course of time, between older and recent stages of the language? To which persons, objects, situations, or acts did and does the word refer? The last question shows that “history” also involves the extralinguistic aspects of meaning, prompting questions such as the following: In what ways did the technique of plowing change through time? When were oranges first imported into Europe? When did politeness distinctions in forms of address arise or disappear? As opposed to most other branches of linguistics, which focus on a specific level of linguistic description (e.g., phonetics, phonology, morphology, semantics, syntax, or pragmatics), etymology takes into account all possible changes in the form and meaning of language. Philip Durkin, in the introduction to The Oxford Guide to Etymology (Durkin 2009, cited under Etymology Textbooks), thus arrives at a more elaborate definition of etymology, which is “the application, at the level of an individual word, of methods and insights drawn from many different areas of historical linguistics, in order to produce a coherent account of that word’s history.” Etymology, then, is not a separate scientific discipline but rather an interdisciplinary practice. The Indo-European languages are among the most intensively studied languages in the world and have been for more than two hundred years. An enormous amount of specialist literature on etymological topics is found in one or more Indo-European languages. At irregular intervals, they are collected in etymological dictionaries; therefore, most of the references in this article will be to such summarizing works. The emphasis will be on the more recent editions and other work relevant to the reconstruction of the Indo-European language family as a whole. Please note that the author was bound by the series guidelines to restrict the number of citations to ten per section. In some cases, therefore, references had to be suppressed for purely numerical reasons.
