Vedic Metre in its Historical Development c11.235

c11.235

(c) With regard to the initial groups it is at least clear that such forms as tuáyā and tuát have a different history from tvám and tvắm, in which the vowel values predominate. In this case it seems probable that the original v cases have been slightly influenced by the u cases. A large proportion of all the instances follow heavy syllables, but there are so many instances at the beginning of the verse that it seems very doubtful whether this is really a cause of the resolution. The form siáma and the word tua shew progressive vocalisation: in the other cases it is diminishing.
