Compare the forms of eka by case and number. Use the table to recognise endings and practise the forms in the matching game.

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.

For numerals, the word itself determines whether singular, dual or plural is used. The table follows the source. Model forms show how the formation rules apply, with earlier forms and variants listed alongside.
