Number words

Number words are adjectives that imply a specific number of items:

  • पञ्च पाण्दवाः
    pañca pāṇdavāḥ
    The five sons of Pandu

Sanskrit's number words generally follow the patterns of the stems we have seen already. Many of these number words have no gender. That is, they are the same regardless of the gender of the noun they describe:

  • पञ्च फलानि
    pañca phalāni
    five fruits

  • पञ्च नद्यः
    pañca nadyaḥ
    five rivers

In this lesson, we'll learn about Sanskrit's number words and how to use them.

eka

eka (“one”) uses the normal pronoun endings. When eka refers to one item, it uses the singular. But eka can also be used in the sense of “a small number” or “a few” of something. When eka has this meaning, it is used in the dual and plural.

Here are the forms of eka in the masculine gender:
