What is the epiglottis?

When an individual consumes food or beverages, they must pass into the esophagus from the throat, in order to enter the digestive system. However, the windpipe (trachea) is in the same area and if food should enter there, it could block the pathway of air to the lungs.


The epiglottis is a cartilaginous flap of tissue that covers the larynx and prevents food from entering the windpipe when swallowing. 


It is located behind the tongue and in front of the larynx. When swallowing, it covers the entrance to the larynx. When a person is breathing, it is upright so that air can easily pass into the respiratory system. 


If the epiglottis becomes inflamed due to infection or injury, it can be very harmful to the individual. They may have difficulty with breathing or swallowing. This condition is known as epiglottitis.


I have included a link showing a diagram of the location of the epiglottis.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
