Paracompact Space is Metacompact

Theorem
Let $T = \struct {S, \tau}$ be a paracompact space.

Then $T$ is also metacompact.

Proof
From the definition, $T$ is paracompact every open cover of $T$ has an open refinement which is locally finite.

Consider some open cover $\UU$ of $T$.

Let $x \in S$.

Then there exists some neighborhood $\exists N_x$ of $x$ which intersects only finitely many elements of $\UU$.

Thus $x$ itself can be in only finitely many elements of $\UU$.

Hence $T$ must be, by definition, metacompact.
