semi-infinite

Bounded one direction

Semi-infinite describes something that extends without limit in one direction but is bounded in another.

In mathematics and physics, a semi-infinite line starts at a point and continues forever: a semi-infinite rod conducting heat.

The term appears in engineering and theoretical contexts where infinite extent applies only partially.
