About feelings

Feelings - sentiments, very similar to the Russian word sentimentality. There is also the French word sentiment, which translates as sentiments. This word is used in the Russian language, in the meaning of "feeling." The use began in the 18th century, and was borrowed from French by means of German. Sentimental means sensitive.
The word "feel", presumably borrowed from the Old Slavonic language, comes from the word "chuv", which means to feel.
It is very difficult to understand all theories of the origin of the word. And not only because the sources are lost. The human language is constantly changing, and with it, the meaning of words is changing. For example, the word idiot. In ancient Greece it made sense, about a man who lives outside the city, does not participate in the life of the city. Now an idiot is one of the stages of a person suffering from (aching) oligophrenia.
From the school biology program, we know that the senses are related to the organs through which our organism communicates with the surrounding world. They are only five - hearing, sight, taste, smell and touch. I think that this is the meaning of the word, the most suitable for the meaning, to what we feel. Anyway in my life.
