How about "sniglet"? I had a book of these about 20 years ago.

neologize: To coin or use neologisms
Well, there you go.

neologism: 1. A new word, expression, or usage. 2. The creation or use of new words or senses. 3. Psychology a. The invention of new words regarded as a symptom of certain psychotic disorders, such as schizophrenia. b. A word so invented. 4. Theology A new doctrine or a new interpretation of scripture.

While on the subject of onomatopoeia, the clan's diet might have played an important role in the development of words, especially if it was heavy in legumes and other such items. To wit, I'm reminded of a once-popular beer: Blatz.

Therefore, what Hollywood today considers hilarious perhaps traces its origins back to the beginnings of language. And the first censors, of course.

We have one: "coin".

Usually applied to phrases, but it works for words too. Unfortunately, though, it has totally unrelated meanings as both verb and noun.


ETA: oops, I see this was already mentioned. Missed this whole page 2!

Although I'm not absolutely sure, I think "neologize" is intransitive, and just refers to something one does, the activity if you want. Whereas "coin" is transitive.

And on the subject of discussion, actually a lot of this would hinge on what exactly one means by a word. It's not as simple a question as it might seem at first glance.

Is a scream of pain a word? We'd probably all agree it isn't. So how about "ouch". Well, it's in the dictionary so it's a word. But on the other hand, it's also a scream of pain. So when does a grunt become a word?

I could be cute and say: when somebody invented the dictionary!

And then, what about whale calls? Are they words? I think the answer is that we really don't know.

So maybe it's an unanswerable question.

As above, so below

Non-linguistic vocalizations, like pheromones and facial expressions, are built in to the nature of a species (and often a point of commonality between multiple species); there's only one thing a given signal can mean, and the number of meanings is limited to the number of basic signals. Words have arbitrary meaning; there's no particular necessity for any given string of sounds to have the meaning a population assigns to it, which means it can evolve as languages do, need translation when dealing with another population, and express an unlimited number of meanings with a limited number of basic components (sounds).

For that reason, I'd expect the first true "words", by which I mean the first sounds or strings of sounds to be assigned arbitrary (and thus alterable) meanings rather than instinctively automatic ones, to have appeared not singly but in groups... because their use for a population that had never had such an abstract and arbitrary communication method before would have been to distinguish between ideas that were too similar for the previous communication system to handle separately. Danger, for example, is a general concept that can take different forms, so you might want a way to tell people which particular kind of danger you mean...
