A small honeycomb-like pit, depression, or cellular cavity, especially one of many covering a surface in a regular pattern.
From Latin favus ('honeycomb') with the diminutive suffix -olus (meaning 'small'). This term emerged in botanical and entomological writing to describe the microscopic features of plant and insect structures with precision.
Faveolus is one of those beautiful scientific words where the structure of the word itself mirrors what it describes—just as honeycombs have regular repeating units, faveoli are repeating pits that follow mathematical patterns. It's linguistic perfection in action.
