🇬🇧
/eɪˈθɜːmɪk/
without heat / non-thermal
Etymology
'athermic' originates from Modern English, formed by prefix 'a-' (from Greek 'a-', meaning 'not' or 'without') + 'thermic' from Greek 'thermos' meaning 'heat'.
'athermic' developed via scientific Neo-Latin/Modern English formation from Greek elements: Greek 'a-' + 'thermos' led to adjective forms such as 'thermic' and the negative form 'athermic' in technical usage.
Initially it meant 'without heat' and over time has retained that core sense, being used specifically in scientific and medical contexts to mean 'non-thermal' or 'not producing heat'.
