El doblete correcto/correcho y sus derivados en la diacronía del español

Abstract Alongside the evolutionary phenomena that arose in the transition from Latin to Romance, there were educated reactions that rescued the original voices to accommodate them, with minor adjustments, to the systems of the Romance languages, at the same time as the patrimonial words, evolved from the same etymons, managed to stay in the spoken register and from there passed to the linguistic system. Such processes gave rise to the development of doublets in the language, pairs of duplicates that, from a common etymological base, gave different results, such as the one formed by the correcto / correcho pair, whose history and geographical distribution (with the exclusive presence of the patrimonial result correcho in the provinces of León and Asturias) itself illustrates phonological processes that, on occasion, go beyond the territorial boundaries established by historical grammars. The derivative adjective escorrecho is related to these words, which enjoyed remarkable vitality in the 13th century and began to decline later until it fell into oblivion, since the Dictionary of Authorities (1929) already defines it as an outdated term whose appearance in lexicographical works does not exceed the margins of the first half of the 19th century. The processes that led to these evolutions will be explained in the present study with the support of databases on Spanish and the main tools of our lexicographical tradition.
