Words about words

Someone had to be crazy about words to compile this exhaustive list of words about words.
I like the following because there's so much human nature and irony wrapped up in them...

aposiopesis

a halting or trailing off of speech caused by the speaker seemingly overcome by an emotion such as excitement, fear, or modesty; a form of brachylogy."When your father finds out...." 

apophasis

mentioning something by declaring that it shall not be mentioned. Same as "paralepsis" and "preterition."

 "I need not remind you to get your Christmas shopping done early."

autoclesis

introducing an idea or subject by seeming to refuse discussion of it, thereby arousing interest.

litotes

understatement by negating the opposite; a type of meiosis. "I was not disappointed with the news."

apocope

loss of the final portion of a word. For example, info from information; cinema from cinematograph, tarp for tarpaulin, demo for demonstration, retro for retrospective, 

antanaclasis

repetition of a word whose meaning changes in the second instance. "Your argument is sound...all sound." -- Benjamin Franklin.
