Etymology
Unknown, likely Germanic. Compare Dutch spraak (“speech”), spreek (“speak”), spreuk (“saying”), sprook (“a story, fiction, tale, or false idea”). First recorded in the late 1890s and early 1900s, suggesting a possible derivation from Afrikaans (i.e. brought back by soldiers returning from the Boer War). With the exception of a few early uses of sprook, the word's spelling has been fixed since it first entered the language. The uncommon ⟨ui⟩ digraph provides further evidence for an Afrikaans or Dutch origin.
