Notes on the forms

The forms follow Whitney’s Sanskrit Grammar. At the end of a word spoken on its own, ḥ represents final s or r; āi and āu appear as ai and au. You can show word accents in the Latin transliteration (IAST). Forms labelled as models follow the formation rules. The game uses the filled cells.

Whitney combines individual attested forms of these words into a shared inflection pattern (§356). The spelling shows his Vedic phonetic reading, such as nadíam. Traditional spelling may contract these sounds to nadyàm.
