Same family: focused, focusing, refocus, focuses, focusless. If you can spell one, the shared part carries to the others.

Where it comes from: “Focus” comes from a Latin word meaning “hearth” or “fireplace,” because it was the center of a Roman home. Over time, the meaning shifted to describe the ‘center’ of attention or activity, and later became a verb meaning to direct your attention closely on something.
