kutra

In Sanskrit, 

kutra (कुत्र) is an indeclinable adverb (avyaya) that primarily translates to "where" or "in which place". 

It serves as the interrogative form within a set of common Sanskrit location-based adverbs:

• Kutra (कुत्र): Where?
• Atra (अत्र): Here
• Tatra (तत्र): There
• Sarvatra (सर्वत्र): Everywhere
• Anyatra (अन्यत्र): Elsewhere or somewhere else 

1. Primary Meanings & Usage

• Interrogative: Used to ask for a location or destination.
  • Bhavān kutra gacchati? (Where are you going?)
  • Śiśuḥ kutra asti? (Where is the child?)
• Indefinite (with particles): When combined with particles like api, cid, or cana, it becomes an indefinite pronoun.
  • Kutrāpi / Kutracit: Somewhere or anywhere.
  • Na kutrāpi: Nowhere.
• Case Equivalent: It is often used as a substitute for the locative singular form of the pronoun kim (kasmin), meaning "in what?". 

2. Rhetorical and Comparative Meaning

In classical literature (such as the Bhāgavata Purāṇa), kutra is sometimes repeated or paired with another word to emphasize a vast difference or incongruity between two things, similar to the English phrase "where is this and where is that?". 

3. Related Term: Kva (क्व)

Kva is a shorter synonym for kutra that also means "where". While kutra is common in standard prose, kva is frequently used in poetic and Vedic verses for metrical reasons.
