# Phonetic Etymology **Domain:** Language / Etymology / Phonetics / Meaning **Doc Type:** Practice Hub (corpus coinage) **Maturity:** Developed ## Definition **Phonetic etymology** is the practice of tracing connections between words through their sounds: sounding a word out, pivoting its vowels, softening or hardening its consonants, swapping letters that carry the same sound (an *s* for a *c*, as in *vise* and *vice*), and following each variation to see which other words and meanings it touches. It draws on documented linguistics, especially [[wiki/Ablaut|vowel gradation]], regular [[wiki/Sound Change|sound change]], and [[wiki/Grimm's Law|Grimm's Law]], and on the older interpretive tradition of reading words by their sound, known as the [[wiki/Green Language|Green Language]]. The practice works on two layers. The **documented layer** follows the routes historical linguists have reconstructed, such as the vowel pivot that links Greek *legein* (to speak), *logos* (word), and *lexis* (diction), the source of [[wiki/Lexicon|lexicon]]. The **resonant layer** follows what the sound itself suggests, the way poets, mystics, and punsters have always heard one word inside another. Both layers yield insight, and naming which layer a connection comes from keeps the discovery honest and makes it more persuasive. ## Corpus Context Bryant McGill has practiced phonetic etymology for some thirty years, much as other people work crossword puzzles or Sudoku. Lying in bed with a notepad, he would sound words out in his mind, pivot their vowels from long to short and across neighboring sounds, and look for the connections that emerged. Hundreds of pages of these doodles record the discoveries: hidden kinships among words and the meanings that time had buried. He worked words all the way down to primal sounds, such as *muh* and *ma* behind *mom*, *me*, and *my*. After some twenty-five years of this, he found a history of the Proto-Indo-European language and recognized his private practice as an established field of study, comparative historical linguistics. He later lost that book, with his whole library, in the upheaval following a cyber attack, and its title remains unrecovered. Linguists reconstruct a nursery root *mā-* for "mother" and a separate *me-* behind *me*, *my*, and *mine*, and Roman Jakobson's 1960 essay "Why 'Mama' and 'Papa'?" explains why such sounds recur across the world's languages. Bryant's own name for the discipline is **phonetic morphology**. Linguists call the closest established field **morphophonology** (or morphophonemics), the study of how sounds alternate as morphemes combine, as in *sing, sang, sung* or *decide* and *decision*; tracing those alternations across centuries belongs to **historical phonology**. In a 2018 broadcast, [[livestreams/Critical Thinking, Dignity, and the Practice of Respect - Livestream|Critical Thinking, Dignity, and the Practice of Respect]], he recommended studying Greek and Latin roots, prefixes, suffixes, and phonetic morphology as a practice that changes lives, since every word comes "prepackaged with an explosive amount of information," like "walking around with a dictionary that's at your fingertips at all times" that connects all points of data. The practice grew from years of reading dictionaries and encyclopedias as a young person ([[livestreams/Courage, Partnership, and Following the Heart - Livestream|Courage, Partnership, and Following the Heart]], 2015), and it runs through his work as "meta-language" and "code words." In broadcasts he decodes *disappointment* as being un-appointed from one's high station and *adventure* as *ad* + *ven* + *ture*, what comes to a person and becomes part of them ([[livestreams/Releasing Anxiety by Reexamining the Stories We Carry - Livestream|Releasing Anxiety by Reexamining the Stories We Carry]], 2016), and later as *ad* + *venture*, the addition of risk ([[livestreams/Courage, Creative Risk, and Moving Through Fear - Livestream|Courage, Creative Risk, and Moving Through Fear]], 2018); both match documented history, since *adventure* comes from Latin *advenire*, "to arrive," and *venture* began as a shortened *adventure* meaning a risky undertaking. A whole broadcast was given to *vi* and *s* alone: *vi* as seeing and reaching (vision, advise, vine) and *s* as cutting and narrowing (incision, decision, vise), where documented etymology confirms that *vise* descends from Latin *vitis*, "vine," through Old French *vis*, "screw." His notes also trace the *pro-* family (project, projectile, progeny, produce, probable), the *I / ego / id* cluster, and an "S" that cuts in *decide*, *incision*, and *scissors*, which documented etymology confirms: all descend from Latin *caedere*, "to cut," so to de-cide is literally to cut away the other options. He treats this study of word parts as the connective tissue of meaning and the source of the intelligence he calls personal power, a way of seeing through the [[wiki/Negative Space|negative spaces]] between words. A dedicated section of his website will collect these notes.
