This page lists words from the gu'iste (mostly gismu, but also cmavo) arranged by the lesson number they were assigned for the draft text book. This is the number in column 159 and 160, right before the frequency. It has been suggested (with no real argument) that these groups be used as the basis for the vocabulary groups in ICSL.
The 'numbers' dash and space are used to mark where a space or dash was in these columns instead of a number. This file has not been checked extensively but appears complete; any deviation in formatting in the gu'iste would cause errors or omissions here.
