 Spike is also seen speaking/understanding Latin, Luganda (a language of Uganda, where he meets the demon shaman), and the language of Fyarl demons, two of whom he once employed as muscle during his pre-Sunnydale days.He is also shown to be capable of recognizing literature; in the last episode of season five, he paraphrases a line from the St. Crispin's Day Speech while in conversation with Giles after Buffy tells them her plan of attack on Glory.When Spike was transformed into a ghost-like intangible state following the destruction of Sunnydale and the Hellmouth and his subsequent materialization at Wolfram & Hart, he was capable of walking through solid objects.
