Years ago, I had read, and then looked up the word for this, but I have since forgotten it, cannot find it, and not being able to recall this word has driven me crazy since.

It's a rarely used or seen word that describes a person who has the ability to, or maybe it was an adjective for just the quailty of ones' speech to be eloquent, spoken with ease and at length and knowledgeably, or at least perceived as knowledgeable/educated on any given topic, via the quality of their speech.

The "at length" part I think was key to include since the word meant more than just being articulate or eloquent in general, it also described the ability to convey a depth of knowledge, whether truly possessed or not.

Something like "the author had the ability to speak _____-ly, and enrapture the audience," or, "the author was _____, able to keep the crowd utterly captivated"

Kind of like a verbosity, but in a good/convincing/skillful way.

It's not a compound word or phrase. It's not / I've searched the thesauruses for erudite / eloquent / articulate / well-spoken / persuasive / verbose / compelling / impassioned / insightful / perspicacious / trenchant... none of them really hit it on the head.

(I think the word was in a Grantland or TheRinger article, FWIT...) Maybe I'm mistakenly conflating the content of the article with another memory of some other word, I sure hope not.

Thanks for any thoughts!

    Could you be thinking of loquacious? – Mynamite Jul 19 at 18:48
  • There's also "Orator" which generally leans towards being very good at it. – Moo-Juice Jul 19 at 18:49

    So basically you are looking for a word that combines eloquence, a characteristic of well-crafted speech, with erudition, which describes the knowledge or wisdom conveyed. Good luck with that. – KarlG Jul 19 at 19:47

    Not wanting to get political, but google "talk like obama". It's far too complicated to express in a single word. – Hot Licks Jul 19 at 21:29
  • Why doesn't 'eloquent' capture all that? – Mitch Aug 19 at 18:26

'authoritatively' implies something about both style of delivery and content. Derived from authoritative: Cambridge online dictionary:

  1. showing that you are confident, in control, and expect to be respected and obeyed: "She has an authoritative manner that at times is almost arrogant."
  2. containing complete and accurate information, and therefore respected: "The book is an authoritative account of the Second World War."

Consider elucidative, the adjective form of elucidate:

(transitive verb) : to make lucid especially by explanation or analysis
(intransitive verb) : to give a clarifying explanation


No term will denote everything that you say, but a few terms come close. One term that may apply is extemporaneous(ly). Merriam-Webster gives one suggestion that denotes the situation and one that denotes the quality suggested:

1a(1) : composed, performed, or uttered on the spur of the moment : impromptu an extemporaneous comment

(2) : carefully prepared but delivered without notes or text

b : skilled at or given to extemporaneous utterance

1a(2) and b capture the sense you are representing. There is skill involved. One has to know their stuff and appeal to an audience to be extemporaneous or speak extemporaneously.

As a teacher of communication myself, I agree with this caveat under "Did You Know?", which specifies that extemporaneous speech is often prepared but unmemorized, with the goal of feeling eloquent and knowledgeable without being canned, stilted, or other common consequences of script-reading:

In general usage, extemporaneous and impromptu are used interchangeably to describe off-the-cuff remarks or speeches, but this is not the case when they are used in reference to the learned art of public speaking. Teachers of speech will tell you that an extemporaneous speech is one that has been thoroughly prepared and planned but not memorized, whereas an impromptu speech is one for which absolutely no preparations have been made.

I closely associate skill in speaking extemporaneously with the concept of sprezzatura, or the air of nonchalance that makes even prepared or trained activities appear natural and easy. Something spoken "at ease" would have this quality.



To expound is the ability to talk at length on a topic, to present and explain (a theory or idea) systematically and in detail.

Voluble means talkative, chatty or naturally flowing in speech. Talking easily, readily, at length, fluent.


  • the author had the ability to speak volubly, and enrapture the audience," or, "the author was voluble, able to keep the crowd utterly captivated"
