Diachronic Phonology & Sound Laws
Analyze how historical phonetic mutations shaped the split of Primitive Common Eldarin into daughter dialects.
Linguistic Codex: Tolkien's Phonological Revisions
Tolkien’s languages are defined by their strict, diachronic Sound Laws. He treated sound changes as absolute mathematical formulas: for example, Primitive Elvish *p, *t, *k regularly voiced to v, d, g between vowels in Sindarin (Welsh-like lenition), but became double-voiceless or remained stops under different criteria in Quenya (Finnish-like aesthetics). The **Sankey sound mutation diagram** mapping on the left illustrates the flow of phonemes from the parent language (left nodes) to the target daughter dialect (right nodes). The **Rule Volatility chart** on the right maps Tolkien's real-life timeline: it shows how many phonological rules Tolkien drafted or modified during different periods of his life (Early, Middle, Late), peaking during his writing of The Lord of the Rings.
