Etymology: The noun in question arises from the adjective "hermetic," which itself has a fascinating origin linked to the figure Hermes Trismegistus, a syncretic combination of the Greek god Hermes and the Egyptian god Thoth. Hermes Trismegistus was credited in late antiquity and medieval times with mystical writings on alchemy, astrology, and the occult. The term "hermetic" originally referred to the secretive, sealed nature of the knowledge attributed to him, especially alchemical texts said to be sealed airtight to preserve their precious contents. By the early 17th century, "hermetic" had taken on a broader meaning related to being airtight or impervious to outside influence, likely inspired by the idea of hermetically sealed containers. This physical sense of complete sealing eventually gave rise to a metaphorical extension, describing ideas, writings, or practices that were esoteric, obscure, or accessible only to a select few initiated in secret knowledge. From the adjective, the abstract noun form emerged to denote the quality or state of being hermetic. In this case, the plural form "hermeticities" would refer to multiple instances or types of such qualities—perhaps the various ways in which something might be sealed off, airtight, or esoterically confined. While not a common form, it follows standard English patterns for forming nouns from adjectives by adding the suffix "-ity" to express a state or condition, and then pluralizing. The root "hermetic" itself derives from Late Latin "hermeticus," which came from Greek "hermētikos," meaning "of Hermes" or "secretive," and the lineage reflects the long-standing cultural association between Hermes and hidden wisdom. The suffix "-ity" entered English from Latin "-itas," used to form abstract nouns, and this process was productive especially from the Renaissance onward when many classical and learned terms were adopted into English. Thus, the noun encapsulates both the literal and metaphorical legacies of secrecy, enclosure, and mysticism carried by its root, capturing the essence of what it means to be sealed off from the common world—whether physically, intellectually, or spiritually.
