The word verse has two meanings. On the one hand, it is closely related to the composition of sacred texts (the Bible and the Koran would be the best known). This text is also used in the field of literature and more specifically in the versification of poems.
In the particular case of the Bible, those who have read it, undoubtedly recognize this particular division above all, where the division into phrases or segmented phrases is a trademark in each of its chapters. In fact, there are verses so widespread in religion that they came to life beyond the Bible.
In the book of Genesis, for example, verse 1: 1: "In the beginning God created the heavens and the earth." However, in the book of the Qur'an, which as we know is the most relevant sacred text at the behest of the religion of Islam, there is also the division into verses within each chapter. There they are specifically called woes and there are more than six thousand two hundred. The verse is the minor division of the Azora or chapters, which in this case are 114.
The function of the biblical verse is eminently practical, since it is a numbering system that brings an order within the various books that compose it. As for its second meaning (by the way, less known and used), the verse is a synonym for free verse.
Historically, poetry was written from a rigid and clearly defined metric structure (decasyllables, hendecasyllables, Alexandrians…), as well as a rhyme, a tone and a timbre. This structure has not disappeared, but with the appearance of avant-garde poetry, free verse, also called verse, prevailed. While the free verse and the verse would be synonymous, some scholars consider that they are not exactly the same (the verses are generally verses of the major art and the free verses are of minor art). The verse does not rhyme and does not have a certain length. Consequently, this characteristic allows the poet to write more freely, without having to express himself through a metric structure that limits his creativity.
From a rigorous point of view it is possible to speak of poems in verse, although this name is very rare, the concept of free verse being used more.
