Not well known, or difficult to understand or see clearly.
From Latin "obscurus" meaning "dark, dim, uncertain." It combines "ob-" (over) with a root related to covering or shading, giving the sense of something hidden in the dark.
Originally, "obscure" was more about literal darkness than confusion. When we say a meaning is obscure, we’re really saying our mind is sitting in the dark, trying to see what’s going on.
