technique for studying the development of languages by performing a feature-by-feature comparison of two or more languages with common descent from a shared ancestor, as opposed to the method of internal reconstruction, which analyses the internal development of a single language over time. Wikipedia s.v. "Comparative Method" The method of comparing languages to determine whether and how they have developed from a common ancestor. The items compared are lexical and grammatical units, and the aim is to discover correspondences relating sounds in two or more di�erent languages, which are so numerous and so regular, across sets of units with similar meanings, that no other explanation is reasonable. Oxford Dictionary of Linguistics (Matthews 1997) The comparative is both the earliest and the most important of the methods of reconstruction. Most of the major insights into the prehistory of languages have been gained by the applications of this method, and most reconstructions have been based on it. Fox (1995) The Comparative Method is the central tool in historical linguistics for historical reconstruction and also classifying languages. A classi�cation done with the Comparative Method is called a genetic classi�cation. The result is that languages are arranged in language family trees. This means that languages are classi�ed according to their genealogical relationships2 and are interpreted as being in relation of child- or sisterhood to other languages. Such a way of classifying entities is called phylogenetic classi�cation in biology; a classi�cation by genealogical relationships. Fleischhauer (2009) The method of comparatistics today is generally known under the not very well-chosen term "comparative-historical method". It constitutes a huge complex of abstract and concrete procedures for the investigation of the history of related languages which genetically go back to some unofrom tradition of the past.

comparative method is a bunch of techniques that are commonly used by historical linguists in order to reconstruct the history of languages and language families. 3 / 20
Determine on the strength of diagnostic evidence that a set of languages are genetically related, that is, that they constitute a ‘family’; 2. Collect putative cognate sets for the family (both morphological paradigms and lexical items). 3. Work out the sound correspondences from the cognate sets, putting ‘irregular’ cognate sets on one side; 4. Reconstruct the protolanguage of the family as follows: a Reconstruct the protophonology from the sound correspondences worked out in (3), using conventional wisdom regarding the directions of sound changes. b Reconstruct protomorphemes (both morphological paradigms and lexical items) from the cognate sets collected in (2), using the protophonology reconstructed in (4a). 5. Establish innovations (phonological, lexical, semantic, morphological, morpho- syntactic) shared by groups of languages within the family relative to the recon- structed protolanguage. 6. Tabulate the innovations established in (5) to arrive at an internal classification of the family, a ‘family tree’. 7. Construct an etymological dictionary, tracing borrowings, semantic change, and so forth, for the lexicon of the family (or of one language of the family). 4 / 20

on many points in historical linguistics, be it the number of laryngeals, the position of Baltic and Slavic, or whether a given word was borrowed or not. We know well that no two etymological dictionaries for the sa- me language or language families are completely identical. Unfortunately, we lack a rigorous check to which degree ex- perts actually agree or disagree in their judgments. We also lack methods for evaluation which would help us to show to which degree a given hypothesis (a reconstruction, a family tree, or an etymology) corresponds with our linguistic data. 9 / 20
