Traditional Judeo-Spanish (18th-19th centuries) according to the Meam Loez series is a corpus-based project consisting of the description of the Sephardic language of the 18th century through a selection of texts from a part of the books (Genesis 1730, Leviticus 1753 and Deuteronomy 1772) which make up the series of Meam Loez (ML), an extensive collection of commentaries on the Bible that follow the weekly order of the synagogue readings. Also taking into account other books of the series written and published in the 19th century, I intend to examine the development of Judeo-Spanish during a period of about 170 years in which it was the language of everyday communication in all areas of society in Sephardic communities, while the ML became the guiding authority on the daily life of those communities.
