Here's another shape that looks suspiciously like a macron (a straight bar over the letter). This time it is over EVA-r (instead of a tail). If this were Latin, this would mean the same as r- or i-with-a-tail. In languages that use Latin scribal conventions, the only difference is that it's easy to write faster if you connect it (so it looks like a tail). Whether it's connected or not, it's basically the same thing when it is word-final.
I have no idea what it means in Voynichese, but it certainly makes you wonder if the r with tail is an abbreviation.
