What does metamorphic mean?
Metamorphic is an adjective meaning related to a transformation in form, structure, or nature. Its best-known use is in geology: metamorphic rocks are rocks that have been changed by heat, pressure, and other geological processes without being completely melted. Examples include slate, marble, and schist. In more general and technical usage, metamorphic can describe a substantial change in form or characteristics, as in metamorphic transformation or metamorphic testing. The word is related to metamorphosis, the process of changing form, and to the Greek idea of metamorphōsis, meaning a change or transformation. The adjective is precise and formal, and it is especially useful when describing a change that alters the fundamental structure or nature of something rather than merely modifying its appearance.

Where does metamorphic come from?
Metamorphic derives from metamorphosis, which comes from Greek metamorphōsis, a change of form, and ultimately from metamorphoun, meaning to change or transform. The Greek combining element meta- and the root morphē, meaning form or shape, also underlie related words such as metamorphose and metamorph. The English adjective became established in scientific usage, particularly in geology.
