(geothermal)
heat from the Earth
Etymology
'geothermal' originates from Greek, specifically the elements 'geo-' and 'thermē', where 'geo-' meant 'earth' and 'thermē' meant 'heat'.
'geothermal' was formed in scientific English from Greek elements (via Modern Latin/coinage) in the late 19th century and became the modern English word 'geothermal'.
Initially, it meant 'relating to the earth's heat', and over time it has retained that specialized meaning in descriptions of natural heat and energy.
