Morphology

horizonless = horizon (semi-transparent) = horizon + less

While the morphological construction is clear, the astrophysical meaning of lacking an event horizon is specialized.

Etymology

Horizonless comes from horizon ('separating line') and the ending -less ('without'), the same root you see in horizontal. So in astronomy a horizonless object is one that has no 'event horizon' — no boundary that traps light — which is why it is not like a black hole.
