What does dissertated mean?
Dissertated is the past tense and past participle of the verb "dissertate," meaning to discourse or write formally and at length on a subject, much as one would in an academic treatise. The verb itself is a back-formation from "dissertation," coined by trimming the noun down to a base form rather than descending directly through centuries of spoken use. Because of this origin, "dissertated" often carries a playful or slightly ironic flavour: speakers reach for it when someone holds forth at tedious length, as in "he dissertated for an hour on coffee roasting." In genuinely scholarly contexts it can be used neutrally to describe sustained written argument, but many writers find it stilted there and prefer simpler verbs such as "wrote" or "discoursed." The word remains relatively rare, appearing mostly in informal or humorous register, yet its transparent connection to "dissertation" makes its meaning instantly recoverable. Knowing it adds a precise, wry option to the vocabulary of talking too much.

Etymology of dissertated
The verb "dissertate" was formed in English as a back-formation from "dissertation," which derives from the Latin dissertare, meaning "to discuss or argue at length," a frequentative of disserere, "to examine or discuss." The root serere means "to join together or arrange in a row," which also gives us words such as "series," "insert," and "assert." The back-formed verb appeared in English usage comparatively recently relative to the noun, and its past tense "dissertated" follows standard regular inflection.
