Don't speak Gothic? Gothic is an ancient East Germanic language spoken during the Dark Ages in Ukraine, Spain, Italy, and Aquitaine. It is the oldest Germanic language which we have a lot of knowledge of, and its vocabulary is highly similar to that of Old English. It is mostly known through a translation of the Bible made in the 4th century by Wulfila, an Ostrogothic bishop, but there are other writings in Gothic, such as a calendar, some records of financial transactions, and an explanation of the Bible known as the "Skeireins". The Skeireins is most likely written in native Gothic, and so it has a more complex structure than the Gothic Bible. Gothic is no longer spoken, and it has no descendants, but it can still be seen in Spanish, with words like "ganso" (goose), and in "Bagme Bloma", a poem by J.R.R. Tolkien written in a reconstructed form of Gothic.
Gothic is written in an alphabet of its own. You will find fonts here, keyboard help here, and transliteration rules here.
