The Dalek Dictionary (feature)

 was one of the features original to The Dalek Book, a Dalek annual published in 1964, which were not so much a story as an informative feature on Dalek society. Although mostly non-narrative (and, as such, not currently considered a valid source by this Wiki), it featured a wealth of new information about Dalek language and culture, as well as other worldbuilding details about ancient Skaro.

It most notably saw the first mention of Yarvelling, who would later appear in the flesh in Genesis of Evil as the inventor of the Dalek War Machine (the first form of Dalek casing). Also mentioned in the Dictionary were War Minister Zolfian and Dalek leader Drenz, two other characters who played a larger part in Genesis of Evil’s account of the Daleks' beginnings.

Story notes

 * In terms of its take on the creation of the Daleks, The Dalek Dictionary inspired the version shown in Genesis of Evil (and, like it, has the Daleks' humanoid ancestors also be called Daleks) but does not match it completely; the Dictionary’s account implies a slow transition from the humanoids to the familiar cyborgs, with the last pacifist leader Drenz being murdered by his own people who then choose to forego individual names, showing that they are already on the way to becoming the militaristic machine-like Daleks familiar to Doctor Who viewers. This means that it is not always clear which form of "Dalek" is being meant in some of the entries; as far as the readers of The Dalek Dictionary knew, Yarvelling, Drenz and Zolfian could all have been machine Daleks rather than members of the humanoid race.
 * The Dictionary employs the adjective "Skaroian" to refer to things from the planet Skaro, whereas "Skarosian" later became the most commonly-used form. It also spells Dalekanium "Dalekenium" (like other material of this period), Magnedon "Magnodon", and Yarvelling "Yarveling".
