Etymology
'hermetic' originates from Medieval Latin, specifically the word 'hermeticus', which derives from the name 'Hermes' (referring to Hermes Trismegistus) associated with certain esoteric and alchemical writings.
'hermetic' changed from Medieval Latin 'hermeticus' (and Old French 'hermétique') and eventually entered English as the modern word 'hermetic' via Middle English and later borrowings.
Initially, it meant 'of or relating to Hermes or the secret writings attributed to him'; over time it evolved to include senses such as 'airtight' (from alchemical practice of sealing vessels) and 'esoteric/obscure'.
