The term 'cold-blooded' originates from the biological classification of temperature regulation in animals. In early biological study, it was noted that certain animals, particularly reptiles and amphibians, did not internally regulate their body temperature, thus being referred to as 'cold-blooded.' This term was initially used in zoology, deriving from the Latin 'calidus' meaning warm and 'sanguis' meaning blood. Over time, 'cold-blooded' began to be applied metaphorically to describe people who lack emotional warmth or empathy. In literature and everyday language, it has become common to associate this term with individuals who act ruthlessly or without compassion, paralleling the demeanor of predators in the animal kingdom.
