tubulaarseks
Tubulaarseks is a term used in Estonian to describe a state of being tubular or tube-like. It is often used metaphorically to describe a physical object that has a long, hollow, cylindrical shape, similar to a tube. This can apply to various things, from natural formations to man-made structures. For example, a long, narrow riverbed or a hollow stem of a plant might be described as tubulaarseks. In a more abstract sense, it can refer to something that is elongated and has an internal passage or void.
The concept of tubulaarseks can also extend to processes or phenomena that exhibit a linear, channel-like progression.
