What is the Shabd Roop of ek in sanskrit?

"Ek" (एक) is a numeral, and numerals in Sanskrit don't decline like nouns and adjectives. Therefore, it doesn't have a "Shabd Roop" (word declension).

However, it can be used with nouns and adjectives, which will then take the appropriate declension. For example:

* Ekā graāmī (एक ग्रामी) - One villager (feminine singular)

* Ekau gṛhaṁ (एकौ गृहं) - One house (neuter singular)

* Eke vāṇijaḥ (एके वाणिजः) - One merchant (masculine singular)

The declension of "ek" depends on the noun or adjective it modifies.
