When the feminine nature is to be indicated the affixes which we shall treat of hereinafter must be used.,
This is an adhikara sutra pure and simple. The phrase 'when feminine nature is to be indicated', must be read in all the following aphorisms upto 81 inclusive. The anuvritti of the word 'pratipadika' should be read into this sutra, from the first sutra, not so, however, the anuvritti of the words 'ङी-आप्'; for we are now going to form words by the application of ङी and आप् affixes.,
