her-MET-ik
(adjective) Completely airtight and sealed; or, completely closed off from outside influence or interference.

From the name Hermes Trismegistus — “Hermes the Thrice-Great” — a legendary Greco-Egyptian figure credited with inventing a miraculous airtight seal used in alchemy. “Hermetic sealing” was named after him, referring to a glass-fusion technique that made containers completely airtight. The word entered English in the 17th century, first in alchemical contexts before broadening into its modern senses.

It was wildly influential during the Renaissance — figures like Marsilio Ficino and Giordano Bruno believed it represented a secret ancient wisdom older than Christianity. Modern Freemasonry, Rosicrucianism, and many esoteric traditions trace spiritual lineage to Hermetic philosophy. The word “hermetically sealed” still carries a faint echo of that sense of sacred, impenetrable mystery.
