Pronunciation
- IPA: /spuːk/[1]
Etymology
It is borrowed from Dutch spook (“ghost”),[2][3][4][5] from Middle Dutch spooc (“spook, ghost”).[2][3][4] The word has Germanic relatives such as Middle Low German spōk and German Spuk (“ghost, apparition”),[3][4][5] but its further origin is unknown.[3][4] The OED finds no certain cognates outside Germanic.[4]
Earliest recorded meaning
A ghost or spectre, often used jokingly; first in American English (1801).[6][3][4]
Semantic evolution
The word first appeared in print in a comic dialect poem attributed to an old Dutchman in Albany, New York,[4] and its early use was American.[6] A related form spuke entered Pennsylvania English by 1830 from German Spuk.[4] The ghostly sense led to a verb, at first “to walk as a ghost” (1867–71)[4][6][3] and “to haunt” (1883),[6][5] and in the 20th century to the senses “to frighten” (1935) and “to take fright” (1928).[4][6] An undercover agent was called a spook by 1942,[6] and the word was also used from the 1940s as a racial slur.[6][4]
