* Vandalic {{IPA|/i/}} was sometimes written {{angbr|e}} by Latin authors.{{r|Reichert|p=96}}

The Proto-Germanic long vowel *{{IPA|/e:/}} is often written in Vandalic names as {{angbr|e}} ({{lang|xvn|Gunthimer}}, {{lang|xvn|Geilimer}}), but it is also represented as {{angbr|i}} {{lang|xvn|Geilamir}}, {{lang|xvn|Vitarit}}.{{r|Wrede|p=91}}

The Proto-Germanic short vowel *{{IPA|/e/}} is often written as {{angbr|i}} in Vandalic{{r|Reichert|p=96}} when it was not preceded by *{{IPA|/r, h, w/}}. For example, {{lang|xvn|Sigisteun}} contains -''i'' because ''g'' precedes the vowel, but {{lang|xvn|Beremut}} retains the *e since ''r'' precedes the vowel.{{citation needed|date=August 2023}} It could either mean that *{{IPA|/e/}} turned into {{IPA|/i/}} in Vandalic<ref name="Onesti2">{{cite book|chapter-url=https://www.academia.edu/691311|first=Nicoletta |last=Francovich Onesti |chapter=Tracing the language of the Vandals |title=Goti e Vandali |date=2013 |publisher=Artemide|location=Rome |isbn=9788875751821 |pages=179–195}}</ref> or that the Vandalic short {{IPA|/e/}} was interpreted as {{IPA|/i/}} by non-natives.{{r|Reichert|p=97}}

Similar to Gothic, Vandalic does not seem to have [[Germanic umlaut|i-umlaut]]. One example of items that demonstrate the lack of umlaut are names that contain the form *{{lang|xvn|ari}} (< Proto-Germanic {{lang|gem-x-proto|*harjaz}} 'army'): {{lang|xvn|Ariarith}}, {{lang|xvn|Arifridos}}, {{lang|xvn|Guntari}}, {{lang|xvn|Raginari}} vs. Old English {{lang|ang|here}}, the latter of which does show umlaut with the Proto-Germanic *''a'' having shifted to ''e''.<ref name="Onesti2" />

Proto-Germanic *{{IPA|/o:/}} is written {{angbr|u}}; {{lang|xvn|Blumarit}} (compare Proto-Germanic {{lang|gem-x-proto|blōmô}}), {{lang|xvn|Vilimut}}.<ref name="Onesti2" /> This could either mean that *{{IPA|/o:/}} turned into {{IPA|/u/}} in Vandalic<ref name="Onesti2" /> or that it is a misinterpretation of the sound by Latin authors.{{r|Reichert|p=98}} In Gothic documents, *{{IPA|/o:/}} is mostly written {{angbr|o}}, but sometimes also {{angbr|u}}.{{r|Reichert|p=98}}

The Proto-Germanic diphthong *eu tends to come down to Vandalic as ''eu''. Take for example the form {{lang|xvn|teudo}}- ('people'),<ref name="Onesti2" /> as opposed to the Gothic {{lang|got|𐌸𐌹𐌿𐌳𐌰}} ({{lang|got-Latn|þiuda}}),<ref>{{cite book |last1=Balg |first1=Gerhard Hubert |title=A comparative glossary of the Gothic language with especial reference to English and German |date=1887 |publisher=Max Niemeyer |location=Halle |page=470 |url=https://archive.org/details/comparativegloss00balguoft/page/n3/mode/2up}}</ref> where it has changed to {{IPA|/iu/}}.<ref name="Onesti2" />

The Proto-Germanic diphthong *ai is preserved as {{IPA|/ai/}}, but tends to become {{IPA|/ei/}} later on. For example, the name {{lang|xvn|Gaisericus}} changes to {{lang|xvn|Geiseric}} in later documents.<ref name="Onesti2" />
