gismu are the Lojban root words. rafsi are the combining forms of the Lojban gismu roots. cmavo are the words that govern the grammatical structure of a Lojban sentence. Attitudinals are cmavo that indicate the speaker's emotional and discursive attitudes toward what is being said.

Vocabulary and Other Study Materials

You need a method to learn the vocabulary. We recommend using one of the LogFlash programs if you have an appropriate computer. See the listings below for computer-oriented Lojbanists. Otherwise, we recommend using the flash cards. Note that the flash cards date to the first baseline and are outdated as to place structures and rafsi. As such, we have reduced the price by $5 per set.

gismu Flash Cards, Instructions and List $10.00 for first set: Each additional set $7.50 with no instructions or word list
Cassette tape supporting Draft Lessons $10.00: --requires package 3 purchase (cassette doesn't match current text order)
