1.)
One of my delights is adjectives that do not admit to comparison.
'Straight'. It is or it isn't--there is no straighter or straightest.
The most interesting one is in the preamble to the US constitution: a more 'perfect' union.
If something is perfect, it can't be more or less so.
Another is 'correct'.
But the one that makes me smile the most is 'unique'.
I love it when someone uses phrases like 'very unique' or 'most unique'.
Speaking of 'correct', there may be more than one mathematical proof/solution; the one that is shortest
is often described as an elegant solution.
2.)
I used to love teaching in the seventies and eighties (ah, yesteryear...)
Some of more memorable phrases are these:
'in reality,'
'what Shakespeare is trying to say', or
'what Aeschylus meant was'.
3.) and misreading:
One student, after reading that Melanthios was punished thus Book XXII of the Odyssey,
(they cut off, with pitiless bronze, his nose and and his ears,
tore off his privates and gave them to the dogs to feast upon,
and lopped off his hands and feet, in fury of anger)
asked 'how could he lope off with no feet?. Sigh. I wonder where that student is today.
At least some in the class got a good laugh out of it.
