anupātin

 The term "anupātin" in Sanskrit generally means "proportional" or "relating to a ratio."

Etymology

The word अनुपातिन् (anupātin) is derived from the Sanskrit root अन् 

(anu, "after, along") and पति (pāta, "fall, depend"), combined with the

suffix -in, which indicates an agent or one characterized by something. 

In classical usage, "anupāta" refers to a ratio or proportion, and "anupātin" 

describes that which is proportional or one who observes or

maintains proportion.

Usage

Mathematical context:  "Anupātin" is often used in arithmetic, algebra, 

or geometry to describe quantities that are mutually proportional. 

For example, if 

$a:b=c:d$, then $a$ is anupātin to $b$ in relation to $c$ and $d$.

Philosophical context: In Sanskrit philosophical or textual discourse,

it can describe proportional relationships in moral, cosmological, 

or poetic constructs.

Literary usage: Ancient Sanskrit literature sometimes uses derivatives 

of "anupātin" to indicate harmony, balance, or coordination, especially 

in metrics (chandas) or music.
