Volume one is a textbook for beginners, and can be easily used as a first year Yiddish textbook at the university level or in adult education classes.
Volume one assumes that you have no prior knowledge of Yiddish and as such, it starts out with the basics - namely the alphabet, how the letters are pronounced, and how to write Yiddish in both print and script.
If you happen to have some experience with Hebrew, you are ahead of the game as Yiddish is written using the Hebrew alphabet, with some minor variations.
Volume one covers units 1-11 of the textbook.
Volume two, which is geared toward intermediate or second year students, picks up where volume one leaves off and includes units 12-20.
Starting with unit eight, most of the units include two interrelated lessons - one of which focuses on a conversation and one on a reading selection.
Throughout, each unit is geared toward a specific theme, such a family, various Jewish Holidays, travel, the Holocaust, the Yiddish Press, Israel, the weather, and more.
Supplementary reading material is found throughout the text.
