单词 bokeh
释义

bokehn.

Brit. /ˈbəʊkeɪ/, U.S. /ˈboʊkeɪ/
Forms: 1900s– boke, 1900s– bokeh.
Origin: A borrowing from Japanese. Etymon: Japanese boke.
Etymology: < Japanese boke (20th cent. in this sense, apparently only in specialist use), apparently shortened < the widely-used pinboke state of being out of focus (1931 or earlier) < pin- (in pinto focus, focal point: see note) + boke blur, fuzziness (18th cent. or earlier), nominalized stem of bokeru to lose focus, to be out of focus (20th cent.; earlier in sense ‘to become blurred, to fade (especially from a darker to a lighter colour)’: 1603 as boqe, boquru, boqeta in Vocabulario da Lingoa de Iapam, glossed ‘the colours appear as red’), specific use of bokeru to become befuddled, to become senile (late 12th cent.), variant of hokeru (derogatory) to become senile (10th cent.).Japanese pinto focus, focal point (1880 or earlier) is a borrowing < Dutch -punt (in brandpunt focal point, lit. ‘burning point’ < brand burning, fire (see brand n.) + punt point n.1, apparently rendering classical Latin focus fireplace, in its post-classical Latin sense ‘focal point’: see focus n.). Slightly earlier use of the Dutch word is attested in a Japanese context, transcribed as burandopyunto (1867).
Photography.
