RHETORICAL DEVICES.

WHAT ARE RETHORICAL DEVICES?

Rethorical devices are the way to use the language effectively in spoken or writting form. So when you use rhetorical devices in a discourse, you are employing different methods to convince, influence or please everybody.  (http://literarydevices.net/rhetoric/).

Some examples:
 The next list contains some rethorical devices that we don't use too much.

• Anacoluthon: A sudden break in a sentence’s grammatical structure: “So, then I pulled up to her house — are you still with me here?”
• Anadiplosis:Repetition of words, especially located at the end of one phrase or clause and the beginning of the next: “I was at a loss for words, words that perhaps would have gotten me into even more trouble.”
•  Antanagoge: The contradiction of a negative comment with a positive one, as in “The car wouldn’t start this time, but it least it didn’t catch on fire.”
• Antimetabole: Reversal of repeated words or phrases for effect: “Ask not what your country can do for you, but what you can do for your country.
• Antithesis: Contrast within parallel phrases (not to be confused with the ordinary use of the word to mean “extreme opposite”): “Many are called, but few are chosen.” The term can also refer to literary characters who, though not necessarily antagonists, represent opposite personal characteristics or moral views.
•  Aporia: A statement of hesitation, also known as dubitatio, in which characters express to themselves an actual or feigned doubt or dilemma: “Should I strike now, or bide my time?”
• Apostrophe: Interruption of thought to directly address a person or a personification: “So, I ask you, dear reader, what would you have me do?”
• Bdelygmia: A rant of abusive language: “Calling you an idiot would be an insult to stupid people. Are you always this stupid, or are you just making a special effort today?”
•  Catachresis: A hyperbolic metaphor, as in “Each word was a lightning bolt to his heart.”
• Commoratio: Repetition of a point with different wording: “He’s passed on! This parrot is no more! He has ceased to be! He’s expired and gone to meet his maker!” (etc., ad absurdum)
• Diacope: Repetition of one or more words after the interval of one or more other words: “People who like this sort of thing will find this the sort of thing they like.”
• Epanelepsis: Starting and ending a phrase, clause, or a sentence, or a passage, with the same word or phrase: “Nothing is worse than doing nothing.”
• Epistrophe: The repetition of a word at the end of each phrase or clause: “I swear to tell the truth, the whole truth, and nothing but the truth.”
• Epizeuxis: Epizeuxis, epizeuxis, epizeuxis! My favorite new word, also called palilogia, refers to nothing more than the repetition of words: “To my fifteen-year-old daughter, everything is ‘boring, boring, boring!’”
• Hyperbaton: Excursion from natural word order in various ways: “Theirs was a glory unsurpassed”; “It is a sad story but true.”
• Polyptoton: Repetition of two or more forms of a word; also known as paregmenon: “You try to forget, and in the forgetting, you are yourself forgotten.”
•  Synecdoche: Substitution of a part or a substance for a whole, one thing for another, or a specific name used for a generic: “A hundred head of cattle were scattered throughout the field”; “A regiment of horse paraded by”; “The swordsmen unsheathed their steel”; “Do you have a Kleenex?”
