Mute: an adjective meaning silent. Pronounced ‘myoot’.
Moot: an adjective meaning without practical consequence. Pronounced ‘moot’.
A moot court is a mock trial conducted to explore a legal case for academic purposes. As the “moot” descriptor implies, nobody ever goes to jail at the end of a moot court.
A moot point is truth claim that does little or nothing to steer the debate in which it appears.
There is no such thing as a mute court or a mute point, except maybe at Gallaudet.
This is sometimes true, but not always. Depends what you think of those academic legal arguments 
To moot literally just refers to the discussion.

There’s another meaning: “proposed for discussion; open to argument”. I believe this meaning is more common in British English, while the “without consequences” meaning is more common in American English.
But in law school it’s what is intended in “moot court.” Students argue cases that are equivocal, not cases that are irrelevent.
ETA: come to think of it, the “without consequences” is probably derived from the earlier meaning.
If a case in law cannot be settled it cannot set a precedent. IANAL, but I am guessing that in certain equivocal cases with major consequences for the immediate parties, a judge can make a non-precedential ruling-- one that applies only to the parties involved, and does not affect future decisions.
Ad nauseam: referring to something that is done to a sickening degree.
Ad nauseum: a misspelling of the above.
Likewise, “in memoriam” refers to something intended to memorialize a person who has died; “in memorium” is a misspelling.
acerb vs acerbic
One, I’ve never really heard the former used; second – they seem to mean the same thing?
Maybe acerbic vs ascorbic.
loose: an adjective. Rhymes with “goose” or “noose.”
lose: a verb. Rhymes with “choose” or “ooze.”
breath: a noun. Rhymes with “death.”
breathe: a verb. Rhymes with “seethe.”
That’s right. A ‘moot’ is a meeting, or discussion; anything that is ‘moot’ is up for debate, so it need not be ‘without consequences’ or even ‘already settled’. Tolkien uses it in his word ‘Entmoot’, a meeting of the tree-like Ents which allows them to debate strategy and tactics in The Lord of the Rings.
An aspersion is an attack against someone’s reputation.
Dispersion is the act of distributing things over a large area or volume (or the result of such an act).
“Casting aspersions” is a thing; it basically means you’re insulting someone.
“Casting dispersions” is sometimes used in lieu of the above, and is nonsensical in this context.

I’ve read the whole thread (so I hope I didn’t do so and still missed it) and am surprised that no one has trotted out the low hanging fruit of:

I can’t tell you how many engineers stick the latter into their presentations, even though electrical circuits very seldom speak kindly of one another.
I keep hearing sportscasters (In particular, but it’s bleeding out into the mainstream…) saying “verse” when they mean “versus.”
It’s like nails on a chalkboard to my brain.
evade vs elude; (indeed, the Wiktionary definition of elude begins “1. To evade or escape from…”
If two words are near synonyms, then it doesn’t matter very much if you get them confused with each other, or swap them over occasionally. That is what thesauruses are for. (or is it thesauri).
My cousin is training a new hire where she works. Apparently this person has glaucoma. A lot of people do to different extents.
This person got words confused and was telling people she had… gonorrhea. 
But if you use the wrong one, it messes up the rest of the crossword puzzle.
