guNa substitutes

[Terrence Brannon]

In lesson III on p.23 Tyberg discusses changes to the root vowel. The
pictorial schematic for creating the 3rd person singular present tense
of a verb is:

(ROOT) + (a) + (ti)

Where ROOT is transformed into guNa substitutes if
(a) ROOT terminates in a simple final vowel
(b) ROOT terminates in a short vowel followed by a consonant [which
brings up a question. is a short vowel any vowel which takes 1 beat,
including e, ai, o, au? or is a short vowel any vowel which also has a
long counter part... a, i, u]

Now, the main question at hand, is the rules for the guNa substitutes
of u or U. The text states """o, or av before vowels"""

Now, what is meant by 'before vowels' ... if they are taking about the
'a' which precedes 'ti' then the question is: The 'a' in the
conjugation is a vowel and will always be there. so the u which is
converted to 'o' or 'av' will always be converted to 'av'.

Are there situations where the 'a' in the conjugation is a consonant,
hence allowing 'o' as a guNa substitute instead of 'av'?

I think I understand what Tyberg is getting at. She didn't provide
enough examples.

Let's take the root 'budh' and create the 3rd person nominative
singular present tense:

budh terminates in a single consonant and is preceded by a short
vowel. Therefore the guNa substitution rule applies.

u has o or av as guNa substitutes. Since the u is before a vowel (dh),
then it changes to 'o' instead of 'av'

Correct.
