Limits of Unpredictability in the Evolution of Word Meanings: How the Study of Semantic Shifts May Help Linguistic Reconstruction

AbstractSince the emergence of comparative-historical linguistics as a separate branch of science in the XIXth century, the study of semantic change has steadily remained one of its weakest areas. Un­like phonetic change, where regular patterns may be established on large amounts of lexical data, semantic shifts have always produced the impression of being random, individual, and complete­ly unpredic­table. Issues of whether phonetically corresponding words in different languages with significantly divergent meanings (such as English clean vs. German klein 'small', etc.) could go back to the same common ancestor were most­ly resolved based on researchers' intuition, and uniform me­chanisms of se­mantic reconstruction were non-existent.

Although the last several decades have seen a renewal of interest in the theoretical aspects of this problem (works by W. Labov, E. Traugott et al.), little has been done in the way of solving it in the interests of practically-oriented comparative linguists who are working on reconstruction of proto-language states. In the meantime, the emergence of such a new subdiscipline as macro-compa­rative linguistics (research on deep-level genetic relationship between languages) has ex­acerbated the issue: the larger the chronological distance between languages, the less reliable are the results of linguistic comparison that are based primarily on phonetic correspondences / similarities and downplay the semantics of the compared items.

Ongoing research by participants of the Evolution of Human Languages (EHL) program shows that semantic change is not as unpredictable as it is often considered, especially within the so-called «basic lexicon», consisting of items that are generally stable over vast stretches of time and are therefore of crucial importance to genetic classification and historical reconstruction. In fact, the majority of semantic shifts, reliably attested in this area of the vocabulary, can be reduced to a highly limited number of possibilities, commonly observed either within particular geographical areas or world-wide. Consequently, at this juncture, it would make sense to focus on building up a database of typical or trivial semantic shifts, which may then be used as an objective basis for eva­lu­a­ting the semantic component of etymological research and for proper semantic reconstruction, rather than spend time on trying to for­mu­late general laws of semantic develop­ment, which, in and out of themselves, have relatively little value for the practicing his­to­ri­cal linguist.
