reticular

The word 'reticular' traces its lineage directly to the Latin reticulum, meaning "a little net", which itself is a diminutive of rete (net). The core concept of a mesh or network has remained remarkably stable. The suffix -ular, also of Latin origin (-ularis), is a common adjectival ending. Thus, the literal construction "pertaining to a little net" evolved seamlessly into the modern scientific and descriptive meaning of having a net-like structure, as seen in biological tissues, neural anatomy, and fibrous materials.
