Loquacious eloquence refers to the ability to express oneself in a fluent and articulate manner, often with a tendency to be verbose and talkative. Some synonyms for this expression could include: verbose articulation, extensive communicativeness, talkative proficiency, chatty expressiveness, and wordy fluency. Other possible synonyms could be garrulous eloquence, voluble articulacy, or effusive verbosity. All of these phrases capture the idea of someone speaking at length with an impressive vocabulary and a skill for stringing together words in a way that is pleasing to the ear. Though sometimes it may be necessary to temper this tendency to talk too much so as not to become overwhelming or tedious.
