[email protected] The conventional wisdom among historical linguists has always been that changes resulting from deliberate, conscious actions by speakers are relatively trivial, confined mainly to lexical innovations, words, and the adoption of a few structural features from a prestige dialect. This paper presents evidence that adult speakers sometimes make deliberate choices that bring about sweeping lexical change and significant grammatical change, and that this can happen in a whole speech community to an extent that can cause the Compara- tive Method to fail in attempts to establish genetic relationship and subgrouping within a language family and to reconstruct proto- languages. Most of the examples that have emerged to date come from language contact situations, but speakers are clearly able to ma- nipulate their stylistic repertoires consciously to bring about signifi- cant internally-motivated change as well. The paper concludes with an argument that such linguistic events only rarely cause serious problems for the Comparative Method, in spite of the fact that the methodology largely relies on the assumption that language change is not subject to speakers' conscious manipulation. 1. Introduction Historical linguists have always known that some linguistic changes result from deliberate, conscious actions by speakers. But the general assumption has been that such changes are relatively trivial, confined mainly to the invention or bor- rowing of new words, changes in lexical semantics, and the adoption of a few structural features from a prestige dialect.
