/am / अम्

/am is the singular /sup ending from the second line, /amauTchaS —

**azva- अश्वॱ + /am → **azvam अश्वम्
(as in azvam pazyAmi अश्वं पश्यामि "I see a horse" )

(Not to be confused with /am' (/pratyAhAra) or /am''' (/tiG replacement).)

Why did **azva- अश्वॱ get second in this sentence, though it gets first in **azvodravati अश्वोद्रवति?

Because of karmaNidvit.... The doer of this **pazyAmi पश्यामि is "I", the object is the horse.
