anumā

 Anumā (अनुमा) in Sanskrit primarily means "inference" or "conclusion drawn from premises," signifying knowledge derived after initial observation or perception.

Etymology

The word anumā is a compound of anu meaning "after" or "following" 

and māna meaning "knowledge" or "measurement." Thus, its literal sense

is knowledge that follows or arises from prior knowledge

Classical Usage in Hindu Philosophy

In the Nyaya school of Hindu philosophy, anumā is regarded as one of

the four pramāṇas (valid means of knowledge) and is essential for 

logical reasoning. It is categorized into types based on inferential

reasoning:

• Pūrvavat – inferring an unperceived effect from a known cause
• (e.g., seeing clouds and inferring rain)
• Śeṣavat – inferring a cause from its effect (e.g., observing a swollen
• river to conclude prior rainfall)
• Sāmānyatodṛṣṭa – inference based on commonly observed patterns
• or regularities

  In practice, anumā can also be for self-purpose (svārtha) or for 
• others (parārtha). It is instrumental in epistemology and underpins
• the method of logical reasoning and debate in Sanskrit philosophy
