# What is univocal?

The term univocal comes from the Late Latin word univŏcus, which refers to that which has a single name or sound. It is an adjective that allows qualifying what has the same value or nature as another element.

Univocal generally refers to what has a single possible interpretation or to what maintains its meaning or essence without variation. For example: “The actions of the president have a single meaning, which is to generate well-being for all members of the community” , “I don’t think that people have a single destiny already written”, “We who make the group have a vision been unequivocal about this problem for many years”.

See the case of the lyrics of a song. Although all listeners hear the same words, their interpretation of the content can vary. In other words, each individual interprets something differently according to their own reading, in turn influenced by multiple factors. It can be said, therefore, that the song lacks a unique interpretation. The idea of ​​univocal, on the other hand, can refer to the correspondence that exists between an element of one set with a single element of another set. This notion appears in the realm of mathematics. Suppose an element in an initial set (known as the domain ) has a single image in the target set (the codomain ). In this case, the mathematical correspondence is unambiguous. Visually, the one-to-one correspondence is reflected in that a single arrow leaves each element of the imaged domain.
