Etymology
The word 'thermographic' is a modern scientific term constructed from classical Greek elements. The first part, 'thermo-', originates from the Greek thermos, meaning "hot," which is related to the verb thermainō, "to heat." The second component, '-graph', derives from graphē, meaning "writing" or "representation," from graphein, "to write." The suffix '-ic' is a common adjectival ending of Greek and Latin origin. Thus, the literal construction "pertaining to heat-writing" logically evolved into the modern technical sense of producing a visual record or image based on variations in heat radiation, typically captured by an infrared camera.
