Why is my text hyphenated? I have a text field. When I enter text in the CKEditor the words look OK. But when I look at the rendered page, it seems as if Drupal has split all word instead of put the entire word in the next line.

For example the word "Materialien" in the screenshot is split and this is not correct. I tried the CSS word-break property, but it seems that something is coming from Drupal and is breaking all the words.
There's some hyphenation library on your page. That's no default Drupal behavior. Find that library and remove it or make it ignore your body fields. Probably some JS library.



OP found hyphenator.js inside MYTHEME/vendor/hyphenator.js.

To remove the library, find out where it got added to the site. drupal_add_js() in D7, or some MYTHEME.libraries.yml library declaration in D8. Or just from the theme's info file.

I'd recommend to fix the hyphenation and simply exclude it for certain fields. This probably can be done with only a few lines of custom JS. Find out how by visiting the docs of that library from the link above.
