Part of speech: adjective

Definitions

1. Having the physiological ability to regulate and maintain a constant internal body temperature independent of external environmental conditions
2. Capable of keeping body temperature stable and consistent through internal metabolic regulation rather than environmental influence
3. Characterized by the capacity to sustain a uniform core temperature through biological heat production and conservation mechanisms

Etymology: "Homoiothermal" is built from two parts: the Ancient Greek "hómoios," meaning "of like kind" or "similar," and the English "thermal," which comes from Greek "thermos," meaning "hot." Put together, the term describes animals whose bodies keep a roughly constant internal temperature, so that the surrounding environment matters less to them. The "homoio-" element is the more revealing one. Greek used "hómoios" for resemblance in general, and the same root gives English "homoeopathy" in the sense of "similar suffering," a coinage that pairs it with "pathos." In "homoiothermal," the resemblance is internal: the creature holds itself at a similar temperature over time, whatever the weather does outside.
