Crystallined

Crystallined is an adjective used infrequently in English to describe something that displays crystalline features or contains crystals in its structure. It is not a standard term in modern technical vocabulary, and most writers would use crystalline or crystallized instead.

Etymology and usage: The form is derived from crystal with the suffix -ine, paralleling other adjectives such as crystalline. In practice, crystallined appears mainly in older texts or in niche contexts, and its precise sense varies idiosyncratically. When used, it typically conveys that a material has a predominantly crystal-like texture or that crystals are evident within a matrix; it does not denote a specific crystallographic symmetry.

Contexts: In geology or mineralogy, a rock might be described as crystallined to indicate conspicuous crystal grains, though modern descriptions would use crystalline or describe a granular texture. In materials science, a crystallined microstructure would be unconventional; adjectives like polycrystalline or single-crystal are preferred. In culinary or decorative contexts, the term occasionally appears in historical writing to describe sugar or candy that forms visible crystals, though crystallized is more common.
