Logorate

Logorate (verb) denotes the act of speaking at length in a verbose, rambling, or tedious manner, often with little value added to the discussion. The term frames such talk as excessive or unfocused and is typically used with a mildly negative or humorous tone. It can be applied to a person who dominates conversations or to a speech that wanders off topic.

Logorate is a back-formation from logorrhea, itself from Greek logos (‘word’) and rhē (flow). English speakers commonly form verbs with the -ate suffix from nouns or adjectives, giving logorate as a verb meaning to engage in the action described by logorrhea.

It is largely informal and not widely found in standard dictionaries. It can take objects with on/about, or function intransitively: “She tends to logorate during meetings” or “He logorates about his achievements.”
