Not only is the sound of this word more elegant in this passage, but the reason for using the word is definite and sound. For hic peccatus, equivalent to peccatio, is correct and good Latin, just as many of the early writers used incestus (criminal), not of the one who committed the crime, but of the crime itself, and tributus, where we say tributum (tribute). Adlegatus (instigation) too and arbitratus (judgment) are used for adlegatio and arbitratio, and preserving these forms we say arbitratu and adlegatu meo. So then Cicero said in manifesto peccatu, as the early writers said in manifesto incestu, not that it was not good Latin to say peccato, but because in that context the use of peccatu was finer and smoother to the ear.

With equal regard for our ears Lucretius made funis feminine in these verses: ii. 1153. No golden rope (aurea funis), methinks, let down from heaven The race of mortals to this earth of ours, although with equally good rhythm he might have used the more common aureus funis and written: Aureus e caelo demisit funis in arva.
