Brit.

/əˌkjuːmᵻˈneɪʃn/, U.S.

/əˌkjuməˈneɪʃ(ə)n/

Origin: A borrowing from Latin. Etymons: Latin acumination-, acuminatio.

Etymology: < post-classical Latin acumination-, acuminatio action of sharpening (1552 or earlier), sharpness, pointedness (1650 in the passage translated in quot. 1651 at sense 1) < acuminat- , past participial stem of acuminare to sharpen (see acuminate v.) + classical Latin -iō -ion suffix¹. Compare earlier acuminate v.In mineralogical contexts after German Zuspitzung ( A. G. Werner Von den äusserlichen Kennzeichen der Fossilien (1774) 178).

1. A pointed or tapering part; (Mineralogy) †a part of a crystal regarded as notionally resulting from acumination (sense 2) (obsolete). Now chiefly Botany and Zoology.
