Gothic was the language of the Goths; the oldest known Germanic language, it is now extinct and left no descendants.
Gothic was the first language that J.R.R. Tolkien studied for his own pleasure, and it may have given an impulsion in the first development of Qenya. Tolkien even attempted to reconstruct some parts of the language. He even composed a poem, Bagme Bloma "The Flower of the Trees"
