Fix line spacing in word with '-' character

Is there a way to fix linespacing in word correctly ?

Using this method doesn't really fix it : https://support.microsoft.com/en-us/office/change-the-line-spacing-in-word-04ada056-b8ef-4b84-87dd-5d7c28a85712

As you can see there are still some spaces and to fix that I have to insert some '-' manually to cut off some words.

This is how I manually changed it and it looks much better :

Is there a way to do this automatically and not have to insert '_' manually everywhere.

Latex does this automatically but I have to write this document in Word.

Do you mean hyphenation, and in Word 2016? You can turn that on in the paragraph settings: Home pane -> Paragraph -> Paragraph settings (the tiny square/arrow at the bottom right)

I suspect this is related to the proofing language you set (Review pane -> Language), so make sure that corresponds to the language you write in, even if you're not using autocorrect.
