Pronunciation

  • IPA (Ecclesiastical): [prosˈpɛk.tus][1]

Forms

prōspectus m (genitive prōspectūs); fourth declension[1]

Etymology

It is from prōspiciō “to look forward, see far” with the suffix -tus.[2][1][3]

Earliest recorded meaning

The OLD's earliest citation is from Ennius, of one's view.[2] Köbler dates Ennius 204–169 BC.[4]

Semantic evolution

It meant the ability to see ahead, one's view, as in Ennius, and in Plautus what is seen, a prospect.[2] In Gellius it meant regard for something.[2]

Medieval Latin in the Low Countries used it for the inspection of dikes and canals.[5] British Medieval Latin used it for sight and gazing out.[6] It gave English prospect in the early 15th century, and through French English prospectus, a printed plan of an enterprise, in 1765.[3]
