- n. A member of a race of extraterrestrial mutants who appear in the television programme Doctor Who and are known for travelling in metallic shells, having monotone, mechanically distorted voices, repeating a limited number of phrases, and being bent on exterminating other beings mercilessly.
Coined by Terry Nation in 1963 for his script The Daleks on Doctor Who. Accounts of how he devised the word vary. Within the Doctor Who universe, the word is related to the name of the people from whom the Daleks evolved, the Kaled people. (Wiktionary)
