Okay this. This one. This. One.

This one bugs me to no end, because I see it EVERYWHERE.

(Actually, it's quite optional to use either word. HOWEVER, one is much preferred over the other in most works)

Lemme show you what I mean:

Her eyes were void of all emotion, making her difficult to read.

The room was void of any light, causing him to trip over something he couldn't see in such darkness.

They walked into the room, skin void of any scars I thought they'd get from the battle.

If you are writing a sentence as shown above, void isn't exactly incorrect, but it is better to use the word devoid. See below:

Her eyes were devoid of all emotion, making her difficult to read.

The room was devoid of any light, causing him to trip over something he couldn't see in such darkness.

They walked into the room, skin devoid of any scars I thought they'd get from the battle.

Here are my screenshots and a brief explanation afterward:

As you can see, either word would work. Sort of. Both void and devoid would work all right in a sentence where it is describing something. Since they're both adjectives meaning relatively the same thing.

But they are slightly different. This sentence:

There are void spaces in the room.

Sounds much better than this:

There are devoid spaces around the room.

But this:

The room was void of any furniture.

Doesn't sound as good as this:

The room was devoid of any furniture.

See how that works? It's a bit confusing, since again, there is hardly a difference in the sentences. Think about it this way. Void means empty (empty spaces), and devoid means lacking (lacking furniture).

I hope this helped, and made sense.

Have a good day/night!<3
