The idea of a comma is used in multiple ways depending on the context. The term can refer to the orthographic sign (,) that allows separating certain elements in a sentence: interjections, vocatives, enumerated objects, etc. It is also used to differentiate between possible meanings and to establish the preposition of a sentence element.
Suppose a woman leaves a note for her husband to let him know that she went out with her friends and that she will be back for dinner. In the text he writes: “I went to have a picnic with Marcela, Ana, Carla and Magalí. I’ll be back before 8 pm ”. As you can see, the woman uses the comma to separate the names she lists: Marcela (comma) Ana (comma) Carla and Magalí.
Depending on the sentence, the use of the comma in our language may be absolutely necessary to give the words the right meaning; similarly, the omission of certain commas can considerably alter the meaning of a message, even making it the opposite of what is intended. For example: “the boxes that are on the table” does not have the same meaning as “the boxes that 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 the comma in written communication is far from being a whim of academics, but it is a fundamental element of our language, which also affects the way in which we express ourselves orally. In speech, the intonation of the two sentences stated in the previous paragraph is very different; broadly speaking, 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, the comma also plays a very important role in writing and speaking, although its use differs. For this reason, part of studying a foreign language is learning to use the spelling signs, both the ones we already know and the new ones.
This sign can also be used to distinguish, in a number, the integer part from the decimal part. For example: 3.5; 586.3; 98.569187.
It is known that in some parts of the world the point is used instead of the comma to separate the whole digits from the decimals, but this is not correct in our language. However, since the point tends to predominate on the Internet, it is very common to find it in articles in Spanish, even in newspapers and publications of relative importance.
According to DigoPaul, coma, on the other hand, is a conjugation of the verb eat, which refers to the action of chewing and swallowing food: “My mother doesn’t want me to eat hamburgers because she says they are unhealthy”, “I don’t think anything I eat from now until the end of the holidays you will be able to overcome this excellent ceviche ”.
In medicine, a state characterized by the loss of the ability to perform voluntary movements, of sensitivity and of consciousness is called coma. 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 cannot move. It is a syndrome linked to a serious alteration of brain functions.
The state that causes an alcohol overdose is called ethyl coma. In general, ethyl coma occurs when the blood alcohol level exceeds 300 mg / dl, although there are certain factors directly related to resistance to this substance, such as the age of the subject, their metabolism, the amount they have consumed. in a given period and the variety of drinks you have mixed.
