I apply now a homophone: "bread."
'tain't no sib'lant morpheme,
But some's comin' round the bend.

They ain't Latinate: zum beispiel, "schlong,"
Germanic. . .no, Yiddish; I'm wrong.

Well, "scream" has some sibilance,
As do "shears," "sears," and "schmears."
"Shells," "sea," sib'lant morphemes.
"Sow," "song," "sin," "stink," "skink," "sighing," "sneers."

All's in this tune is words like "snake". . .
A sib'lant hiss, make no mistake,
And will slither across the floor,
Then in snake-speak: sib'lant morpheme.
Your skins he'll score.

"Spell," "spit," "shush!" "rose"—bon mots;
This song has none, it seems.
Sheesh! Sib'lant morphemes
Surge to site where digits stream.
So, shanty seethes uncivil rants,
Silliness-sotted shriveled cants.

Devolve to phonemes: "a," "ure," "co," "an," "on," "mi," "ed";
Not for long. Sib'lant morphemes: "science syzygy sheds."
That makes no sense, youse knows. . .
Semanticists shift in chaise.

Surreal song's winding down. Signoff sure's stretching hisses:
"Seize, size, sleaze," sirs says.
