etāṁścānyāṁś ca

 The phrase "etāṁścānyāṁś ca" in Devanagari 

script is written as "एतान्स्यान्यांश्च"

Explanation

• एता — represents "etā" (these)
• ऽṁस — "ṁs" denotes the anusvāra over "s" in "āṁs"
• यां — "yāṁ"
• श्च — "ś ca" combines "ś" (palatal sibilant) and "ca" (and)

When combined correctly according to Sanskrit phonetics, 

it forms एतान्स्यान्यांश्च, which captures both the pronunciation 

and traditional spelling conventions.

The Sanskrit phrase "etāṁścānyāṁś ca" can be broken down as follows:

• etāṁs (एतांश्) – accusative masculine or neuter plural of 
• etat (this/these), meaning “these”.
• cānyāṁś (च अन्यांश्) – "ca" (च) is the conjunction “and”; 
• anyāṁś (other parts/portions) comes from anya (others) 
• plus plural ending, meaning “the other parts” or “others”.
• ca (च) – reinforces the conjunction, literally “also” or “and”.

Thus, the phrase etāṁścānyāṁś ca roughly translates to:

“these and the other parts as well” or simply “these and others” 

in English.

In grammatical terms:

• etāṁs is plural accusative, referring to specific items.
• anyāṁś is plural accusative indicating remaining items 
• or portions distinct from the first set.
• ca connects the two groups.

This phrase is commonly used in classical Sanskrit prose and 

poetry, as well as in philosophical or scriptural passages, whenever 

one wants to refer collectively to a particular set and the 

remaining items.

You can also render it more fluidly in Sanskrit texts as:
एतान्स् च अन्यांश्च (etānś ca anyānś ca).

This preserves the meaning while following traditional Sanskrit 

compound and conjunction rules.
