152. For all the processes of external combination

For all the processes of external combination—that is to say, in composition and sentence-collocation—a stem-final or word-final is in general to be regarded as having, not its etymological form, but that given by the rules as to permitted finals. From this, however, are to be excepted the s and r: the various transformations of these sounds have nothing to do with the visarga to which as finals before a pause they have—doubtless at a comparatively recent period of phonetic history—come to be reduced. Words will everywhere in this work be written with final s or r instead of ḥ; and the rules of combination will be stated as for the two more original sounds, and not for the visarga.
