scienter (comparative scientius, superlative scientissimē)[1]
Etymology
It is from Latin sciēns (“knowing”) + -ter,[2][1][3] the present participle of sciō (“to know”) with the adverb suffix.[1][3] De Vaan takes the verb to be probably a back-formation from nesciō (“not to know”); it goes back to Proto-Italic *skije/o- (“to know”), and if the sense “know” grew out of “distinguish, decide”, to a root meaning “cut off, incise”, Proto-Indo-European *skh₁-i(e/o)-.[4] He compares Ancient Greek σχάω (skháō, “to slit open”).[4]
Earliest recorded meaning
Köbler dates it from Cicero,[5] who in De oratore speaks of speaking scienter et perite, “skilfully and expertly”.[2][6]
Semantic evolution
Its classical sense is skilfully, with expert knowledge.[2][7] Cicero uses the comparative of Isocrates' skill in his field and the superlative of a man explaining how a celestial sphere worked;[2][6] Caesar uses the comparative of people who dug tunnels under a siege ramp the more skilfully because they had large iron mines,[2] and Nepos uses it of playing the pipes well.[2][7]
The sense knowingly, consciously, appears in Pliny the Younger's Panegyricus, in an oath that calls down the anger of the gods if the speaker deceived knowingly,[2][6] and Augustine sets it against ignoranter, unknowingly.[7] This became the usual medieval sense:[8][3] British writers used it for knowingly or wittingly and also for deliberately, and John of Salisbury writes in 1160 of a man who knowingly kept silent in a tumult.[3]
