Part of speech: adjective

Definitions

1. Describing tissue or material that does not contain or relate to bone in structure or composition

Etymology: "Nonosseous" is a plain formation: the prefix "non-", meaning "not" or "without", attached to "osseous," an adjective meaning "bony" or "of bone." "Osseous" comes from Latin "osseus," itself from "os," the Latin word for "bone," which also gave English terms such as "ossify" and "ossuary." The result is a purely descriptive coinage for tissues or structures that lack true bone, such as the cartilaginous skeletons of sharks and rays or certain soft-bodied parts of animals. Because it combines an English prefix with a Latin-derived root, it reads as a technical term rather than a word with a long popular history, and its meaning can be worked out directly from its two halves.

Synonyms: cartilaginous, soft-boned
