prius praedīcam, lit. I will first say in advance.
4. Hendíadys (‛εν δια δυοιν, one through two) is the use of two nouns joined by a conjunction, in the sense of a noun modified by a Genitive or an Adjective; as,—
febris et aestus, the heat of fever;
celeritāte cursūque, by swift running.
5. Prolépsis, or Anticipation, is the introduction of an epithet in advance of the action which makes it appropriate; as,—
submersās obrue puppēs, lit. overwhelm their submerged ships, i.e. overwhelm and sink their ships.
a. The name Prolepsis is also applied to the introduction of a noun or pronoun as object of the main clause where we should expect it to stand as subject of a subordinate clause. Thus:—
nōstī Mārcellum quam tardus sit, you know how slow Marcellus is (lit. you know Marcellus, how slow he is).
Both varieties of Prolepsis are chiefly confined to poetry.
6. Anacolúthon is a lack of grammatical consistency in the construction of the sentence; as,—
tum Ancī fīliī ... impēnsius eīs indignitās crēscere, then the sons of Ancus ... their indignation increased all the more.
