1-4: Masculine Gender with -vanta at the end - Bhagavanta

Vanta-kārantapulliṅgo Bhagavanta-saddo vuccate
The Masculine Gender with -vanta (and -manta) at the end
is illustrated with the declinable word Bhagavanta This form is given as Bhagavant in the modern grammars, and Bhagavantu in the Pāḷi grammarians, and Ven. Devamitta gave it as part of the -a declension. It seems preferable though, to give it as -vanta, which is the characteristic ending. Other nouns with similar declension include: sīlavanta, hīmavanta, yasavanta. Similarly declined are nouns like cakkhumanta, satimanta, etc., but then they decline satimā, satimanto, etc. etc.
