The PDF below is a wordlist of the Continental Celtoid conlang called Vindonian that I have been working on for at least a year now. Most entries include significant etymological material (and some commentary).
(For an explanation of what I mean by “Celtoid”, see my article called “Celtic and Celtoid”: https://vellaunos.ca/2021/03/26/celtic-and-celtoid/ )
This wordlist is certainly not complete, and many inconsistencies and errors may well be found in it. But here it is nonetheless…
December 25, 2021 – significant modifications to the orthography (bh > v, dh > ð, gh > h), the phonology (initial z > s, initial sV > tsV, full disappearance of intervocalic -s-, all double consonants reduced to single consonants) and the morphology.
