Relating to or resembling a grating, lattice, or framework with small openings; having a grid-like or mesh-like structure.
From Latin cratícula (diminutive of cratis, meaning grating or wickerwork), + -ar (suffix making adjectives). The root relates to woven or interlaced structures.
Scientists studying porous materials and filters use craticular to describe how tiny holes and passages create strength—the same principle that makes honeycomb so efficient.
