Hermes is a name with a few similar sounding words, all of which (that I'm aware of) are related to traits of Hermes:
Hermeticism: a spiritual tradition based on Hermes as corresponding with Egyptian Thoth, associated with magic, writing, intellect, language's roots, and more. Etymology traces this to Latin hermeticus, derived from the name of the Greek god Hermes.
Hermeneutics: an art and science of deep interpretation, especially of sacred texts. Etymology traces this to Greek ἑρμηνεύς (hermeneus, "translator, interpreter"), which is of unknown origin, but a folk etymology for hermeneutics associates it with Hermes.
Hermetic seal: Wikipedia's page on Hermeticism notes "Hermes Trimegistus supposedly invented the process of making a glass tube airtight (a process in alchemy) using a secret seal. Hence, the term "completely sealed" is implied in "hermetically sealed" and the term "hermetic" is also equivalent to "occult" or hidden."
Hermit and hermitage: a life setting (physical, emotional, or both) based on isolation from other humans, originating from "the Greek ἐρημίτης (erēmitēs), "of the desert", which in turn comes from ἔρημος (erēmos), signifying "desert", "uninhabited", hence "desert-dweller"; adjective: "eremitic"."
Hermit seems to be the only word sounding like Hermes but not etymologically linked to Hermes. Is there a clear link, historic or otherwise, between hermit and Hermes?
For what it's worth, the Greek for "interpretation" and for "of the desert" are quite similar, sharing their beginning but differing in their middle and end:
ἑρμηνεύς - hermeneus - interpretation ἐρημίτης - erēmitēs - of the desert
