Pronunciation

  • Classical: [ˈpraːk.tɪ.kʊs][1]
  • Ecclesiastical: [ˈprak.ti.kus][1]

Forms

prācticus (feminine prāctica, neuter prācticum); first/second-declension adjective[1] The TLL notes that the word never became fully Latin: manuscripts often write it in Greek letters with Greek endings, and only the feminine singular occurs in Latin form, besides one neuter in an inscription.[2]

Etymology

It is borrowed from Ancient Greek πρακτικός (praktikós, “active, effective”),[3][2][1] from πράσσω (prássō, “to do”).[1]

Earliest recorded meaning

Fulgentius speaks of the vīta practica, the active life, as opposed to the contemplative one;[4][5][6] the OLD's only citation, an inscription, uses it of “effective” proof.[3]

Semantic evolution

In Late Latin it means “active, effective”, of a life or discipline turned towards action,[2][4] and Boethius uses the feminine.[2]

Medieval writers set it against contemplative and speculative: Aldhelm speaks of leading the contemplative life before the practical one,[7] Thomas Aquinas uses it of what is directed to action,[8] and Roger Bacon of applied sciences such as practical alchemy and astrology.[7] It also became a noun, “practitioner, lawyer”, from about 1180.[6] In Neo-Latin it means “experienced, skilled”, as of a painter learned in his art (1470).[9]

Etymonline traces English practice to Medieval Latin practicō, from this adjective, and practicum (1904) to its neuter.[10]
