interiectus m (genitive interiectūs); fourth declension[1] Lewis and Short and Gaffiot spell it interjectus.[2][3]
Etymology
It is formed from Latin intericiō (“to throw or place between”) + -tus, a noun of action from that verb.[1][4][5]
Earliest recorded meaning
Its first use is in Cicero's De natura deorum, where the moon is suddenly eclipsed by the interposition of the earth (interpositu interiectuque terrae).[1][4][5]
Semantic evolution
The TLL records it once in Cicero, then in Tacitus and in poetry.[4] Besides the placing or coming of one thing between others, it was used of an interval of time: in Tacitus, Tiberius is not softened by the lapse of time (interiectu temporis).[1][2][3] Apuleius speaks of setting stones down at random intervals.[2]
