Is there a distinction between world space or global coordinates?

[AlanMattano]

In the documentation, I can find terminology switching between world space, global coordinates

https://docs.unity3d.com/Manual/Transforms.html

For scene construction, it is usually sufficient to work with local coordinates for child objects but in gameplay it is often useful to find their exact position in world space or global coordinates.

I was assuming was the same till a tutorial make me think about it.

Is there any distinction between world space or global coordinates?
or World space can we call it global space?

In UnityScripting C#, What's the distinction between global coordinates and world space?

[Fabian-Haquin]

World and global are synonym.

You can say “World coordinates”
To me you are being a bit more specific by saying coordinates than space but space is easier and shorter to say and write than coordinate.

Ex: I made an awesome new shader, it’s a screen-space ambient occlusion shader!
Ex: I don’t understand how to convert my object coordinates to screen space, help!
