## Definition

A **connected normal space** is a topological space which is both connected and normal.

## Facts

- Any connected normal space with at least two points has cardinality at least that of the continuum. This follows by considering an Uryoshn function that separates the two points, and observing that connectedness forces the Urysohn function to be surjective.
