It is known as the appreciation of the act and the result of the appreciation: that is, to value or estimate someone or something. Appreciation, in this way, can be equivalent to affection. There are different forms of interpersonal affection, appreciation shows affection towards another person through a positive view of another person. A person who appreciates another values ​​her virtues, has esteem and consideration for the other.

If there were a scale of feelings, we could say that affection is less intense than love. That is, a father does not care about his children, but he loves them. The same happens between members of a couple or other family ties. In contrast, among co-workers or neighbors, there may be esteem such as appreciation and not love. This is due to a lack of emotional closeness or even limited knowledge that these people may have with each other.

This type of affection, although it may be more superficial than true friendship in which there is deep trust, also nurtures personal self-esteem since personal relationships to varying degrees also bring happiness when these relationships are positive. This type of relationship is defined by cordiality and respect towards the other. In addition to the pleasure that these types of links produce.

In this type of interpersonal links there may be a greater distance or loss of relationship since these types of links are usually caused by a specific event, for example, they coincide in the same job or in the same university course. When two people are really friends, they keep in touch during their summer vacations and make plans more often.

A person may have few true friends throughout his life since deep friendship implies commitment and dedication of time. However, a person knows many people for whom he has a sincere appreciation, since this bond to be more superficial requires less commitment.

Appreciation, on the other hand, is used as a synonym for appreciation, a concept that refers to the increase in the price of one currency compared to another. When one currency appreciates against another, its value increases. For appreciation to be possible, the exchange rate should not be fixed (since, in that case, the price would not change).
