I'm thinking of a word that rhymes with "sonic"

What's that noise, a screwdriver or a hedgehog? Either way, it sounds like "sonic."

There are obviously a huge number of words ending in the suffix -ic, so I'd recommend guesses that form a two-syllable rhyme with "sonic" or else we'll be here a very long time. (Of course, the rhyming words can be more than two syllables.)

I can't remember the word I was going to try. Guess I need one of those cool memory-enhancing devices.

2 - Et in Arcadia ego is quite gory,
And as mnemonics go, memento mori
I'd fain avoid. Though older than the hills,
That sum quod eris still gives me the chills.

Not: mnemonic

Is it how I'm feeling when I don my devil suit?

I'm hearing some sounds unstressed, and discordant, with overtones, and orchestral!

These plates just keep a-slippin' and a-slidin' all over Gaea.

4 - That demonic lawyer, advocatus diaboli,
Drafts Satan's contracts none too shabbily.
As primus inter pares, he reigns well
O'er all the other lawyers found in hell.

5 - Verbis defectis musica incipit;
I'm not sure on "unstressed," and so I'll skip it.
Symphonic and harmonic I adore,
Yet, horribile dictu, half the store
Sells cacophonic blare, sung sloppily;
Alas, their sales reflect vox populi.

6 - Tectonic forces slowly get their way:
Suaviter in modo, fortiter in re.
As Turkey drifts from Asia toward Moldova,
Thus terra firma turns to terra nova.

Not: cacophonic, demonic, harmonic, mnemonic, symphonic, tectonic

Oh, my aching back!
This pain just won't go away :(

8 - Tempora mutantur, nos et mutamur in illis,
Except of course for chronic situations;
Then tempus fugit, speedy as Achilles,
Sed non mutamur in our humble stations.

//Sorry to hear that, Jenni.//

Not: cacophonic, chronic, demonic, harmonic, mnemonic, symphonic, tectonic

Might it describe the distant deeps where I like to hang out when I don my devil suit?

It's spring! I think I may need some of this elixir to improve my energy levels.

Lee Majors and Lindsay Wagner?

The people who lived around Sparta
Used to say no more words than they oughta.

Thought of this after seeing news of Levon Helms' death today. As I recall, it describes his performance in Coal Miner's Daughter.

10 - Don't summon de profundis, or you'll rue it;
Some beasts should stay in situ, so don't do it.
The chthonic fiends you conjure with that codex
Just might come back to bite you in the podex.

11 - I cannot lie: in vino veritas,
But as for me, just fill my demitasse
With gin and tonic. Look, some robins! See 'em?
The spring's the perfect time for carpe diem.

Not: cacophonic, chronic, chthonic, demonic, harmonic, mnemonic, symphonic, tectonic, tonic

12 - Habeas corpus? Maybe not much longer;
Bionic parts already make us stronger.
It seems right now we're halfway in between a
Humble birth and deus ex machina.

13 - If tace is Latin for candle, as they tell,
Laconians were awfully fond of flame;
Since silence is golden, as they knew full well,
Ignis aurum probat they might claim.

Not: bionic, cacophonic, chronic, chthonic, demonic, harmonic, laconic, mnemonic, symphonic, tectonic, tonic

Unstressed is a#11

5/16 - I guess I must have been too hooked on "phonic."
It's clear, post facto, that your word's "atonic."
Perhaps with future guesses, Deo volente,
I'll heed that old advice: festina lente.

Not: atonic, bionic, cacophonic, chronic, chthonic, demonic, harmonic, laconic, mnemonic, phonic, symphonic, tectonic, tonic

I'm being black-plagued with ideas, but they're all a little foetal.
A column can form a solution.
This music is charged with energy.

I'll feel like a really stupid person
if I don't suggest something like a very powerful symbol

Yesterday I saw 3 deer gamboling in the meadow.

#19 P.S. Rodney---my uncle was actually in The Coal Miner's Daughter. He was the guitarist in Loretta Lynn's band. (They played themselves) I think he only spoke about 10 words in the entire movie...he introduced her onstage twice!

My love of deep igneous rocks transcends the physical!

18a - If salus populi suprema lex,
Bubonic plague's a crime, or one might say so.
But no mens rea causes its effects:
Instead, mens sana in corpore reo.

18b - "In utero" once made me contemplate
A tiny babe in embryonic state.
O tempora, o mores! Now the phrase
Just makes me think of Cobain's golden days.

19a - Cogito ergo sum, and yet I rue
The fact the converse clearly isn't true,
For morons do exist; you can't ignore 'em:
Infinitus est numerus stultorum.

19b - Though phallic is well-known, most don't know there is
The yonic for potestas mulieris.
Are chauvinists to blame, or maybe Freud?
That casus belli I would fain avoid.

//Not playing possum; I'll reply to the remaining guesses as soon as possum.//

22 - Ah, Pluto and Plato: how to explain 'em?
For Pluto, Mickey's dog, it's cave canem.
For Plato, with his metaphor so grave,
The spooky shadows murmur: cave cave.

Pertaining to an indigenous member of the Scottish Rite?
(two guesses)

Artemis shot arrows in the wild;
Her temple, ancient wonder, used this style.

18c - Ionic columns and ionic bonds
Are strong, yet Tempus edax soon responds
He has them, like all earthly things, outgunned. He
Laughs aloud: sic transit gloria mundi.

18d - Caveat emptor! The car lot tries
Some shady tricks to fool the eyes.
The import's a junker: its brakes are shot;
Its electronics, in toto, are not so hot.
And yet its glossy wax job often hooks
A buyer based on how the Fiat lux.

20 - Ah, such a fitting scene, by nature blessed;
That truly dulce et decorum est.
Could "halcyonic" be what your intent is?
If that's way off, I'll seem non compos mentis.

//I think I'm caught up through #24, though I have doubts about #20.//

I have a feeling that there is a clue or clues in the Latin insertions, especially since the rhymes require occasional modification of traditional pronunciation. Could Crambo's word refer to rules that govern how a particular phoneme is pronounced in different contexts?

Second guess: wouldn't it be, um, amusing in a certain way if I'm looking way too deeply for a clue?

25a - An autochthonic people might protest
The status quo if they have been oppressed:
"Why do the colonizers like to bully us
With specious doctrines such as terra nullius?"

25b - Lux e tenebris, says the Scottish Rite.
Masonic lore is highly recondite
So, ipso facto, it gets fearful looks
From some who see tenebrae more than lux.
That's not the kind of fame I bet you want
Unless it's oderint dum metuant.

26 - Ibid., 18c, I think? If not, let me know.

28a - There is a clue-cum-theme, I must admit.
Alas, poeta nascitur, non fit,
And so my allophonic rhymes might shock:
That's not intended, just a bit ad hoc.

28b - When Caesar uttered iacta alea est,
He spawned a saying that's become iconic,
And though his act Fortuna Brevis blessed,
Its almost-homophone is quite ironic.
By letting his ambition rule the day
And risking all he had, it's no affront
To note he threw all other things away
And might have said that iacta alia sunt.

Why am I twitching like this? Oh, my poor basal ganglia.

30 - Eheu, it is a torment fit for Dante
To feel your muscles twitching sua sponte,
Since myotonic dystrophy would make 'em
A neuronic battleground; and so, pax tecum.

This kinda guy can be mad, bad, and dangerous to know.

32 - Though Childe Harold's Pilgrimage most weigh
As Byron's magnum opus, just pro se
I think the eerie Manfred is his best;
De gustibus non disputandum est.

This round has me so depressed, I think I'm just going to sit by the window over there, staring blankly and not talking to anyone.

#20
It grieves me to report that halcyonic, while it does indeed rhyme and is beautiful of ear, is not the dear/deer word. The next time I saw those deer, they were cavorting in the spring!

20/36 - Cave īdūs Martias! You'd best drive slow,
For in the spring the merry deer do frolic;
Vae victis in collisions so bucolic.
Oh dear, oh deer: what homophonic woe.

Minus the prefix, part of thisʻs
Already in the " nots", whether cheers or hisses

Greek, the origin of this, but you wonʻt find ʻer
Much in Greek texts; they were much more
Straightforward, and thought it was a bore
To be too __ __ __ __ __ __ __ __ in oneʻs
Speech much like being __ __ __ __emistic; the funʻs
In the talking about the bad --smoothly to be
Sure -- but with what you might hear or see
Emphasizing the substance, not the sound

1950, was dissed by Prof. Sterling Dow for his in-

Now, just as if Iʻd won this round of the game;
Bu if I havenʻt, thanks all the same.

38 - Most histrionic folks are far from calm;
They advertise their moods ad nauseam.
They will, no doubt, ham up their dying day so,
While sighing, "Qualis artifex pereo!"

This type of scale includes five whole steps and two halves. It might have been used in Babylon and Sumeria.

Quid est veritas, you wonder; and I
Should clue you toward my modus operandi.
This Crambo word would please the ear and brain
In literary, not symphonic, vein.

//Even if Crambo's word I knew,
I would not post it here. For you
Doth thrill my eye and my mind,
With poetic replies, all of a kind.

No guess, just respect.

//Gratias tibi ago! For this word,
A rather stringent theme has been incurred,
Yet fun to write. So thanks for your respects;
The theme is rigid: dura lex sed lex.//

As famous alcoholics. Truly, bonum
Vinum does laetificat cor hominis;

Is the lack of coordinating conjunctions in your Latin phrases significant, or just a result of their placement in your verses?

48 - The latter, Jim; I've used a few, quod vide,
Sed nothing key is hidden in absentia.
As always, I revere your sapientia
Et spirit nec temere nec timide.
Ipsissima verba aren't, as you might think it,
As grave as form. Labor omnia vincit.

ETA:
Oops, I missed your guess; that's quite ironic.
But, hic et nunc, it's not asyndetonic.
If that were it, I'd cite the old and creaky
Quote from Caesar: "Veni, vidi, vici."

like Viserion, Rhaegal and Drogon in many respects?

50 - "Hic sunt dracones" is meant to scare away
From blank spots on a map, and yet I'd say
I'm not sui generis when it makes me
Want to seek draconic beasts, where'er it takes me.

It be the adjective describing a nonstandard vernacular?

Form, you say. The form is iambic pentameter with a lot of lines having an extra unstressed foot. Is there a name for that? I couldn't find one, unless it's "Tyronic" in honor of Count Rugen. No hidden guess here ;-)

Would this "form" be a pertaining to a geometric shape?

55 - I'm fond of conic sections, that's no fabula;
It's hard to match the grace of a parabola.
Ars gratia artis brings the duty

I'm not fond of this, and it's not sour grapes

Yankee Doodle went ad vicum
Riding equuleum;
Stuck a feather in capellum,
Called it verbum meum.

Might we be talking here about something mixed up and jumbled, or as in the case of your marvelously inventive responses, specifically Latin and vernacular words mixed all together? (If this is the correct guess, Gratias enim note numerus LIX.)

Ave, James, and yes indeed! Crambo's word was macaronic, referring to verse that mixes two languages, usually Latin and a vernacular. Macaronic verse often features contrived inter-language rhymes for humorous effect, and it may include bilingual puns.

I tip my capellum to James as the winner, and a hearty gratias vobis ago to everyone who played. Well done, amici et amicae!

Wait! I call for the photo!

And optime factum to you, Buck, keeping up your macaronic responses longer than you might have planned.

Ignore #62! I was in a rush for work and I thought #59 was a guess!

For once, I was quite sure that my guess was a wiiner, thanks to Buck's very helpful clue. Usually, I'm shocked when I win a round. Anyway, on to the next round which you'll find here.
