claste

Claste is a term that can appear in different contexts, but there is no single universal definition. In some cases it is encountered as an alternative spelling or misspelling of "clast," a standard term in geology for a fragment of preexisting rock.

In geology, the correct term is clast. Clasts are the individual pieces that compose clastic rocks such as sandstone, shale, and breccia. These fragments originate from weathering and erosion of larger rock masses and are transported before being deposited and lithified. While "claste" may be seen in informal writing or typographical errors, it is not the established term in scientific usage.

In biology and medicine, the root -clast comes from the Greek klastos meaning broken, as in osteoclast, a cell that resorbs bone. The form "claste" is not used as a standalone word in standard nomenclature, though it may appear in etymological discussions or in coined terms.

As a proper noun, Claste can be used as a fictional place name, brand, or project title in various works. When encountered in that sense, its meaning is determined by the source rather than by a universal definition.

Etymology: derived from Greek klastos meaning broken; usage is context-dependent and often limited to specific disciplines or creative works. See also clast, clastic, osteoclast.
