Hebrew

Hebrew was an Earth language in which the Gospel of Mark was originally written. (PROSE: Byzantium!)

Bernice Summerfield was fluent in this language. (PROSE: Just War)

Behind the scenes
Several settings in the Doctor Who universe come from Hebrew words. They include, but are not limited to:
 * The planet Sheol. In Hebrew, this means "hell." Located within Sheol, ironically, is the city of Heaven. (PROSE: The Ruins of Heaven
 * The colony planet Ha'olam. In Hebrew, this means simply "the world" and is the word used in real-world Hebrew to describe Earth. Judging by this and obviously Jewish characters in the novel (like Shoshana Rubernstein), it is safe to assume that the planet has Jewish/Hebrew origins. (PROSE: Seeing I)

The song The Daleks' only lyrics are "מה קורה," (ma kor'eh) "what is happening" in Hebrew, repeated over and over again.
