Sindarin Phonetics

This section explores the later phonetic developments in the Sindarin language of the 1950s and 1960s; for earlier (in-universe) changes see the phonetics discussions for Ancient Telerin and Old Sindarin. My analysis also compares Sindarin to the early conceptual stages of the language in order to trace the conceptual evolution of Tolkien’s ideas: Noldorin (1930s), Early Noldorin (1920s) and Gnomish (1910s).

My analysis of the Sindarin phonology draws heavily on David Salo’s work in A Gateway to Sindarin (GS/31-72), but there are quite a few places where my analysis differs from his, mostly because a lot of material has been been published in the time between when he wrote his book (2004) and when I did my research (mainly 2018-2019). I also consulted a number of other articles by Bertrand Bellet (NPE, VASN) and Thorsten Renk (ENPP), and relied very heavily on the work of Roman Rausch (HPG, HPITN) for comparisons with the Gnomish and Early Noldorin conceptual stages of the language.

I consider this analysis more or less “complete”, in that I’ve explored the majority of the etymologies of published Sindarin words, but that doesn’t necessarily mean it is correct in all places, since frequently the evidence is ambiguous and open to multiple interpretations. There are also a couple areas, notably Sandhi sound changes at morpheme boundaries, that I only barely cover. For Sandhi changes in particular I recommend consulting A Gateway to Sindarin (GS/51-59), which despite its age is in the only thorough exploration of this topic that has been published.
