Relating to or resembling alveoli; containing or characterized by small cavities or cell-like structures.
From Latin alveolus (small cavity, hollow) + -ary (suffix meaning 'relating to'). The Latin root possibly derives from alveus (channel or trough), reflecting the idea of small contained spaces.
The alveolary structure of honeycomb inspired engineers and architects for centuries—nature's design of hexagonal chambers maximizes space while using minimal material, a principle we now copy in everything from car crash protection to spacecraft.
