Forms

ciência f (plural ciências)[1] Houaiss records the old forms sciençia (1394), sciãçia (14th century), çiemça (1454), çieçia (1484), çiemtia and esciençia (15th century).[2] Until the spelling reforms (1911 in Portugal, 1943 in Brazil) the word was written sciencia.[3] Feijó in 1734 marks Sciencia as the form in use, and Vieira in 1871 still sends the reader from ciência to sciencia.[4][5]

Etymology

It is borrowed from Latin scientia (“knowledge”), a learned word.[2][6][1][7] The Latin noun is formed from sciēns (“knowing”), the present participle of sciō (“to know”), with the abstract suffix -ia.[1][8] De Vaan derives the verb from Proto-Indo-European *skh₁-i- (“to incise”), and the DHLF also suggests that it first meant “to cut”, then “to decide”.[9][8]

Other languages took the same Latin word: Spanish ciencia, recorded from Berceo, and French science, from 1080.[10][8]

Earliest recorded meaning

Lorenzo's chronology cites the Chronicle of 1344 with as artes e sciencias e os outros saberes “the arts and sciences and the other kinds of learning”, and a royal document of 1370 with the formula de nosa ciencia certa “of our certain knowledge”.[11] Houaiss takes 1370 as the first date.[2] Cunha dates the spelling sci- to the 14th century and gives the old sense as “knowledge, learning, information”.[6]

Semantic evolution

The medieval word meant knowledge in general, and in charters a ruler's knowledge of what he decreed, as in de nosa ciencia e poder assoluto “of our knowledge and absolute power”.[11] Bluteau in 1712 defines it in the philosophical sense as certain and evident knowledge through causes, and notes that the ancients counted only three sciences, logic, physics and moral philosophy.[12] Folqman in 1755 separates certain knowledge from learning or erudition.[13] Today it chiefly means a systematic body of knowledge gained by observation and research, and each of its branches.[2][14]
