Brit.

/ˌsɪntᵻˈleɪʃn/, U.S.

/ˌsɪn(t)əˈleɪʃən/

Forms: 1500s sintillation, 1600s– scintillation.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French scintillation; Latin scintillātiōn-, scintillātiō.

Etymology: < (i) Middle French, French scintillation flash of light (a1506), action of sparkling (early 16th cent.; 1740 in specific use in astronomy), and its etymon (ii) classical Latin scintillātiōn-, scintillātiō, denoting an eye disease (Pliny), literally ‘sparkling’, in post-classical Latin also denoting the twinkling of stars (from 13th cent. in British sources) < scintillāt- , past participial stem of scintillāre scintillate v. + -iō -ion suffix¹. Compare later scintillate v.

I. The action of sparkling and related senses.

a. The action or result of scintillating; emission of sparks or small flashes of light.
