half-space
Narrow fixed width
Half-space has two distinct technical meanings.
In typography, it's a space character narrower than a standard space—typically half the width—used for fine-tuning text layout: Insert a half-space between the number and the unit.
In mathematics and physics, half-space refers to either of the two regions created when a plane divides three-dimensional space, or a line divides a plane.
