5.227

「又諸念聲至可由語發」者，此下經部別破生名。如多念聲生一名時，前聲至現、後聲未來，後聲若至、前聲已謝，不可聚集，云何生名？亦無一名分分漸生，如何名生可由語發？

On "Moreover, sounds of various moments... can be generated by speech": below this, the Sautrāntika separately refutes the production of words. If the sounds of multiple moments produce a single word: when the preceding sound is present, the subsequent sound is future; when the subsequent sound arrives, the preceding sound has already perished. They cannot assemble together, so how could they produce a word? Nor does a single word arise gradually part by part; how then could the arising of a word be generated by speech?
