The term "metamorphic" derives from the Greek words "meta," meaning "change," and "morph," meaning "form" or "shape." Therefore, one can infer that metamorphic refers to something that undergoes a transformation in form or structure.
In geology, for example, metamorphic rocks are those that have transformed from an original igneous or sedimentary form due to changes in temperature, pressure, or the presence of chemically active fluids. This transformation can result in changes in mineral composition and texture.
In a broader context, "metamorphic" can also refer to any process of change or evolution, suggesting a transition from one state to another, whether it be in literature, biology (as in the metamorphosis of insects), or other fields. The overarching theme is one of transformation and adaptation.
