The basic core of Iermansc is the Vulgar Latin as spoken in Germania in the first five centuries AD. Along with this core is a fairly large amount of terms from Germanic, borrowed before the full assimilation of the Germanians. Later in the language, learned influence introduced a large amount of words derived from literary Latin. Words from the first two categories undergo a set of characteristic sound changes. In this version, the sound changes presented would actually make the name of the language Iermónsc!
