Neologism composed by the union of two elements: 1. etymo- e 2. sophy.
“primitive word,” 1570s, from Greek etymon, neuter of etymos “true, real, actual,” related to eteos “true,” which is perhaps cognate with Sanskrit satyah, Gothic sunjis, Old English soð “true.”
Word-forming element meaning “knowledge,” from Old French -sophie, from Latin -sophia, from Greek -sophia, from sophia “skill, wisdom, knowledge,” of unknown origin (source: www.etymonline.com).
Etymo derives ultimately from the Indo-European root *AS-, which expresses the idea of being.
Sophy comes from the Latin sophia, translated from the greek sofia, wisdom, knowledge. Its root is not yet defined: for the majority of scholars is *SAP-, connected to the idea of juice/ flavor/hindsight.
Etymosophy result: wisdom of the essence of the word.
