Science

C.1300, “knowledge (of something) acquired by study,” also “a particular branch of knowledge,” from Old French science, from Latin scientia “knowledge,” from sciens (genitive: scientis), prp. of scire “to know,” probably originally “to separate one thing from another, to distinguish,” related to scindere “to cut, divide,” from Proto-Indo-European root *skei- (cf. Greek skhizein “to split, rend, cleave,” Gothic skaidan, Old English sceadan “to divide, separate” (v. shed)) (source: www.etymonline.com).

The Indo-European root is not yet defined, for the majority of scholars is *SKA-/*SKI- which expresses the idea of cutting, splitting; for others it is a cognate root of observing, witnessed by the Sanskrit ci-Ke-ti.

Etymosophy result: observation by analytical process.
