I found this while looking for something else:
genuine - 1596, from L. genuinus "native, natural," from root of gignere "beget" (see genus), perhaps infl. in form by contrasting adulterinus "spurious." Alternative etymology is from L. genu "knee," from an ancient custom of a father acknowledging paternity of a newborn by placing it on his knee.

Boy, does *that one sound like a folk etymology.

well, it's certainly an interesting ankle on it...

Boy, does *that one sound like a folk etymology.

Yes it does. Most relate genuinus 'innate, native, natural' with the same root that noun genus 'race, stock, breed' and the verb gigno 'to beget, bear' come from. There is another word genuinus in Latin which means 'of or belonging to the cheek' (dentes genuini 'jaw-teeth, back-teeth') from gena 'cheek'.

another word genuinus in Latin which means 'of or belonging to the cheek'

Which would add a touch of irony if indeed, cheek comes from a word meaning jaw and jaw from a word meaning cheek.

And not all etymology is genuine.

Nor is all that is genuine tongue in cheek.

Tongue in cheek risks upper cut linguectomy.

linguectomy

Is there a medical term glossectomy? Linguasection? I wonder if jaws and knees are connected? Both crooked.

Dear jheem: I found several sites mentioning "glossectomy",
none for "linguectomy". I'm biting my tongue.

Don't they tend to use Greek roots in the medical terminology? -ectomy is ultimately from the Greek.

Glossalgia or glossodynia avoid mixing Latin and Greek.
So I'm biting my tongue again.

Dear Bill-- Not a problem. I was just wondering out loud if there was a procedure called a glossectomy? And after googling, I see there is. Didn't US Grant have one? Or did he just die of tongue cancer? In re your other two words: is there a difference between glossalgia and glossodynia?

Dear jheem: I don't remember seeing either of those words
before I found them a few minutes ago. I see no likely difference. Never heard of Pres.Grant's problem. Oral cancers from snuff are not rare, but I'll bet they hit the cheeks or gums first. Good thing lies don't cause cancer. Or maybe fear of it would encourage veracity.
Trying to think of a fancy word for Pinocchio's problem.

Trying to think of a fancy word for Pinocchio's problem.

How about rhinauxesis? Rhinogigantasm?

Dear jheem: better than I could do. But to be mischievous,
I challenge you to incorporate idea that it is a punishment.

Yes, Bill, I thought what is it about Pinocchio's nose. Sure it grows, but it's also as a punishment for his lying. Greek has trouble with this sort of compounding, but Sanskrit would be perfect for it, sometimes combining a whole bunch of words together into a 4 or n word compound. Let me think about it and get back to you.

The Greeks were reputed masters of the art of wilful misrepresentation to achieve goals. Odysseus was much
admired for his skill at deception. If Greeks had a
Pinocchio, he would have been rewarded by enlargement
of the phallus, not punished by protrusion of the proboscis.

In thinking about infant on father's knee, it occurred to me
that the Roman diaper service was so inadequate that to take
an alimentary canal with a loud noise at one end and no
reponsibility at the other onto the paternal knee would have
not been at all appealing.

Ya don' spose the nose was a whaddaya callit? like Aphrodite spranging from Zeus's brow?

Dear Faldage: Old Zeus must have been c...headed. Twice?
After a time Zeus developed the mother of all headaches. He howled so loudly it could be heard throughout the earth. The other gods came to see what the problem was. Hermes realized what needed to be done and directed Hephaestus to take a wedge and split open Zeus's skull. Out of the skull sprang Athena, full grown and in a full set of armour. Due to her manor of birth she has dominion over all things of the intellect.

Athena, Aphrodite, iceberg.

Aphrodite, OTOH, sprang from the foam on the ocean that billowed up after Ouranos' genitalia were lopped off by Kronos and thrown in. I never did understand Botticelli putting her on the halfshell. Something to do with Santiago as a slogan and les coquilles Saint Jacques no doubt.

As did the iceberg, IIRC.

The lechuga or the the tip off the glacier?

Athene's mother was Mnemosyne, the goddess of memory. Zeus was told that if Mnemosyne had a son, he would dethrone Zeus as Zeus had his father, the aforesaid Chronos. So when Mnemosyne became pregnant, Zeus turned her into a fly and swallowed her.

Bingley

I don't know why he swallowed that fly.
Perhaps he'll die.

I would use glossalgia for pain in the tongue without stimulus, and glossodynia for pain caused by some form of stimulation which would not usually cause pain. But that's just me.
