Crystalite Naming Structure

While cataloguing the most precise possible name of a crystalite is a widespread goal of crystalite enthusiasts and scholars, most people are quite content with a generalized name. This is consistent with people's regard towards non-crystalite animal families, as well; a sparrow and a starling are both songbirds, a trout and a bass are both fish, a fly and an ant are both insects, and a bobcat and a leopard are both cats.
A crystalite's name has four parts to it, especially when generalized: the animal name, the vegetation name, the suffix to indicate its nature, and--frequently overlooked--the adjective to help set it apart from similar crystalites in everyday conversation.

The Animal Name (Prefix)

The animal portion of a crystalite's name is usually the most specific part of the crystalite's identification. The most generalized affixes still identify the animal family, such as feli- for cats and cani- for dogs. How detailed or generalized a person gets with a crystalite's animal inspiration varies; a wolfish crystalite could be considered lupi- or included in cani- with dogs.

The Plant Name (Infix)

The plant portion of a crystalite's name is most likely to be overgeneralized by all but gardeners, farmers, and foresters. Most people who can’t identify what plant comprises part of a crystalite’s form will default to a small selection (listed below) of the larger group of plant classifications:
Is it green?

Use -lif- if it's leafy, -gras- if it's weedy, or -veg- if it's generic vegetation. You can even use -mos- if it's mossy or lichen-like.

Is it brown?

Use -tri- if it's tree-like or skip directly to -wud- for any woody plantlife.

Is it sharp?

Use -bry- for a texture that resembles briars, thorns, or cactus needles.

Is it wiggly?

Use -rut- for brown roots (or go directly to -tri- for tree-like), or use -vyn for green climbing plants and vines.

Is it a protrusion?

Use -sid- for small brown objects (seeds and nuts) and -fung- for usually-obvious mushrooms. If it's colorful, use -blum- for flower-shapes or -frut- for fruits and berries.

The Crystalite Type (Suffix)

While -ite was used in all of the plant name examples above, it is not the only suffix for crystalites. Fen crystalites, the most common type of crystalite that are always partially inspired by photosynthesizing plants, have names ending in -ite. Fey crystalites, which are also photosynthesizing but bear the further mark of a human-inspired form, have names ending in -ine. And fel crystalites, the only crystalites that subsist on heat instead of light and lack photosynthesizing inspirations, have names ending in -ium.

The Adjective

The adjective portion of a name is the most regional and subjective, yet frequently most helpful part of a crystalite's identification. An ursitrite--a common wild crystalite inspired by bears and trees--could vary from a small, relatively reclusive creature based on a black bear and an oak tree to an enormous, fearless beast based on a grizzly bear and a redwood tree. To tell them apart without having to remember the "long name" (scientific name) of the animals or trees, people will simply add an adjective.
A black bear ursitrite in a temperate region could be called a climbing ursitrite, a hill ursitrite, a coal ursitrite, or simply a common ursitrite. A grizzly ursitrite in a cooler mountainous region could be called a fishing ursitrite, a river ursitrite, a brown ursitrite, or a boulder ursitrite.
