Now I, coming at it as a Sanskrit student and not a Hindi student, heard
it more as "Hindi doesn't always pronounce the final -a; it's often
dropped." Which also at least has some degree of truth: many
consonant-final words (with no virama) in Hindi are Sanskrit borrowings
that do end in -a (e.g. the name Raam/Raama, etc).
