そ and も meaning in その中でも


I need some help in understanding the meaning of そ and も in その中でも. I
understand that の中で by itself carries the meaning of among but I could not
figure out the contribution of the two other hiraganas the phrase.
Additionally, why do の中で means among? Anyone know the etymology of the word.




I think you're parsing it wrong:
[その](https://jisho.org/word/%E5%85%B6%E3%81%AE) is a single word, so
「その中でも」means something like "Also inside/among that" (with
[も](https://jisho.org/word/%E3%82%82) meaning "also, too").

As for 「の中で」, [「中」](https://jisho.org/word/%E4%B8%AD) also means "among", so
「Xの中」 means "Inside X", "Among X" (like 「Xの右」 means "To the right of X").
