To those persons who are attempting to memorize all 1728 forms of the Ca affix from Tables 5(a) through 5(l) in Section 3.5.3: You might find it helpful to review the alternate means of showing Extension explained in Section 6.3.5 via tone on a verbal adjunct (use a neutral default verbal adjunct an-n if you have to). In this way, you only have to memorize 288 forms of the Ca affix (the NRM and RPV forms of the DELIMITIVE extension) instead of the full 1728 forms. Just a suggestion.
I think a beginner should first learn these 288 forms + the way to mark extension on a verbal adjunct (which is more or less just one of six tones (+ mood)). After mastering this simpler way, one can come back and memorize the rest of table 5, but at this point, one is already able to express everything that table 5 lets you encode, so learning this table will not add more meaning to your words, but it will make your sentences shorter.
