Question

How do I add a half-space between words using Word 365 and Windows 10?

Solution

There are a couple of settings that affect horizontal spacing on the “Advanced” tab of the “Font” dialog.  “Scale” is probably the best one for what you want.  Select all the spaces between words (you can handle the spaces between sentences differently if you want)

        

and click on the little symbol in the lower right corner of the “Font” panel on the “Home” tab.  This will open the “Font” dialog box.  (On most desktop versions of Microsoft Word, Ctrl+D will also do this; I don’t know about Word 365.)  Go to the “Advanced” tab, click on the “Scale” dropdown, and select 150%.

    

This will make the spaces 50% wider than normal, effectively adding a half space between words.

        

Even though the “Scale” field has a dropdown, you can type any number (up to 600) into the box.

You can get a similar effect with the “Spacing” field, but that is measured in points rather than percent.

Selecting all the spaces like this is tedious.  An easier method is to use Find and Replace to change the formatting:
