The idea from coma It is used in multiple ways according to the context. The term may refer to spelling sign (, ) that allows certain elements to be separated in a sentence: interjections, vocations, enumerated objects, etc. It is also used to differentiate between possible senses and to establish the preposition of a sentence element.

Suppose a woman She leaves a note to her husband to let her know that she went out with her friends and that she will return for dinner. In the text write: “I went to have a snack with Marcela, Ana, Carla and Magalí. I will return before 20 hours ”. As you can see, the woman uses the comma to separate the names she lists: Marcela (coma) Ana (coma) Carla and Magalí.

Depending on the sentence, the use of comma in our language may be absolutely necessary to give words the right meaning; similarly, the omission of certain commas can significantly alter the meaning of a message , even turn it opposite to the desired one. For example: "the boxes that are on the table" do not have the same meaning as "the boxes, which are on the table"; the first sentence speaks of "some boxes", which, unlike the others, "are on the table", while in the second "there are only boxes in that place, on the table".

The need to use comma in written communication away is to be a whim of academics, but it is a fundamental element of our language, which also affects the way in which we we express orally. In speech, the intonation of the two sentences stated in the previous paragraph is very different; in broad strokes, we can say that in the second we must pause where the comma is and lower a few tones before continuing to speak.

In other languages, such as English and Italian, comma also plays a very important role in writing and speaking, although its use differs. For this reason, part of the study of a foreign language is learning to use the spelling signs , both those we already know and the new ones.

East sign it can also be used to distinguish, in a number, the whole part of the decimal part . For example: 3,5 ; 586,3 ; 98,569187 .

However, given that the point usually prevails on the Internet, it is very common to find it in articles in Spanish, including newspapers and publications of relative importance.

Coma, on the other hand, is a conjugation of verb eat , which refers to the chewing and swallowing food : “My mother doesn't want me to eat hamburgers because she says they are not healthy”, “I think that nothing I eat from here at the end of the holiday can overcome this excellent cebiche”.

In the field of medicine , the state characterized by the loss of the ability to perform voluntary movements, sensitivity and consciousness is called comma. The concept, in this case, comes from the Greek word kôma, which translates as "deep sleep" .

The person who is in a coma, therefore, is unconscious and can't move. It is a syndrome linked to a serious alteration of brain functions.

It is called ethyl coma to the state that causes an overdose of alcohol . In general, ethyl coma occurs when the level of blood alcohol crosses 300 mg / dl, although there are certain factors directly related to resistance to this substance, such as the age of the subject, its metabolism, the amount consumed in a given period and the variety of drinks you have mixed.
