Disinvent is an obvious compound of the prefix dis-, here having a reversing force, and the verb invent.

The origin of persiflage all comes down to sound. English persiflage is borrowed from French persiflage, derived from persifler “to banter” and -age, a noun-forming suffix. Persifler combines per-, an intensive prefix meaning “thoroughly,” and siffler “to whistle, hiss.” Siffler in turn comes from Late Latin sīfilāre, from Latin sībilāre, also “to whistle, hiss.” This perfectly expressive verb yields English sibilate “to hiss” and sibilant “hissing,” which, in phonetics, characterizes such sounds as the –s– and –zh– in persiflage. We can well imagine how the teasing repartee, for example, of two sweethearts in a romantic comedy, sizzles with sibilant sounds, but for all the “hissing” of persiflage, its raillery is light and good-natured. Persiflage entered English in the mid-18th century.

English foment ultimately comes from the Latin noun fōmentum “a soothing dressing or compress (hot or cold), a remedy, alleviation.” Fōmentum is a contraction of an earlier, unrecorded fovimentum or fovementum, a derivative of the verb fovēre “to keep warm, protect from the cold, refresh, ease.” The Latin neuter suffix –mentum is used to form concrete nouns from verbs, such as armāmentum “sailing gear, tackle,” from armāre “to fit out with equipment or weapons.” Foment entered English in the 15th century.
