Git for non-programmers, or how to make git work not line by line?

Question

git

Interested in the following.
There is a paragraph of text and there is a need to control versions of the text. Text split into large paragraphs
The problem is this: if the person editing the text decides to put a comma in the middle of a paragraph, the entire paragraph (which is one line) will be deleted and a new paragraph with a comma added - this is how it will look in the commit. If there are 20 sentences in a paragraph, then correcting the smallest error will result in 19 of the twenty sentences being marked as redacted, but this will not be true.
Purpose: to make (if possible) git have some other delimiter that defines "line" and not the actual line break (for example, dot, ellipsis, exclamation point, and question mark). Thus, by putting a comma, it will be possible to commit with one changed "line" - the sentence.
Do you know of a means to do this?

Answer 1

do not write a paragraph in one line, do hyphens every 80 characters, for example.

Answer 2

git diff --color-words=.

Answer 3

Highlighting is up to the editor and version viewer - so that they can mark the specific change location.
You can also use markdown there paragraph = \n\n
