In order to make your writing more colorful and vivid, you need to use some rhetorical devices. If I were to write a post about health care, for instance, I would probably use an opening line that is somewhat shocking in order to perk interest in my audience. Maybe the following sentence would suffice:
'Can anybody explain to me how it is possible that insurance does not cover a baby's feeding pump and feeding bags when the aforementioned baby has silent aspiration?'
And that's what we call a rhetorical question since its purpose is not to obtain the information that the question asks, as I don't really expect an explanation from my audience. If I followed up my opening line with another interrogative, saying:
'Why would insurance cover the feeding pump and feeding bags after all, when eating by mouth would only kill my baby?'
it would be a further example of a rhetorical question, combined with another rhetorical device called irony. My words are ironical because if taken literally, they express understanding and agreement, whereas my intent is to convey quite the contrary. (Mind you, verbal irony should not be confused with sarcasm, which is the tone of voice that often times accompanies irony). Another example of a rhetorical device is the metaphor. In order to illustrate how to use a metaphor, I could say:
'Health care costs have skyrocketed' or
'It makes my blood boil that we have to pay several hundred dollars every month just for medical equipment despite our expensive insurance coverage'
In these sentences, I used figurative language to imply a comparison between a rapidly rising rocket and the rapidly rising medical costs as well as between anger and a hot liquid. Metaphors should not be confused with similes, which are more explicit comparisons and use the words 'like' and 'as'. A simile would be
'Dealing with the healthcare system as the parent of a disabled child is like being a mouse trapped in a maze'.
Now when I say:
'I cannot really complain about our insurance coverage because it saved us from financial annihilation considering that it has paid millions of dollars for Izzy's medical bills already'
it might seem like I'm using a hyperbole for emphasis, but I'm not. In order to qualify for a hyperbole, an expression has to be exaggerated, so I would have to use the expressions 'billions' or 'zillions of dollars'. Naturally, the writer can employ a multiple of rhetorical/literary devices within one utterance. See if you can spot all of them in the following sentence:
'I know that my thinking got corrupted as a result of growing up with universal health care and consequently my mind is full of crazy ideas, such as health care should be a person's inalienable right, but regardless, a system that causes millions to go bankrupt while an unregulated monopoly makes huge profit on people's misery is broken."
