Book excerpt: As an Indo-European language, Armenian has been the subject of etymological research for over a hundred years. There are many valuable systematic handbooks, studies and surveys on comparative Armenian linguistics. Almost all of these works, with a few exceptions, mostly concentrate on Classical Armenian and touch the dialects only sporadically. Non-literary data taken from Armenian dialects have largely remained outside of the scope of Indo-European etymological considerations. This book provides an up-to-date description of the Indo-European lexical stock of Armenian with systematic inclusion of dialectal data. It incorporates the lexical, phonetic, and morphological material in the Armenian dialects into the etymological treatment of the Indo-European lexicon. In this respect it is completely new.
