Dalek (language)

Dalek was the language of the Daleks.

The Dalek word for sewer was the same as the word for graveyard. (TV: The Witch's Familiar) Swearwords also existed in Dalek. When reading text about the Professor Helen Clay from the Pathweb, the Twelfth Doctor noticed and ignored swearwords about what the Daleks viewed to be inferior species. (PROSE: Twice Upon a Time)
