When I was working on my video game project I came across a few toponomies that I couldn't find much or any anything about, thus I'm setting about trying to construct Latin forms of these toponomies based on research. One of them is Apchier, google finds nothing, but if I had to guess is likely an old castle. Working from An introduction to old Occitan by William D. Paden I've reconstructed a hypothetical Latin forum as *Appcarium as -ier comes from Latin -aricum, which is common in place names. I added another "p" based on the word apelar from Latin Appellare and I reduced the ch to c as a typical gallo-romance trend is for c to become ch. How'd I do? Does this look sensible?
