Over time, human language has become increasingly complex, so that elements that complicate the understanding of some words have been added. For this reason, rules are required to facilitate understanding of the methodology, symbols, stress, and sounds that are more complicated.
It is not easy for children to learn the rules about the correct use of B and V, since both sound the same, that is why when they are in the initial stage of writing, they are often confused and, consequently, they abound. misspellings.
The correct use of B and V is one of the orthographic points that causes most errors when a text must be written in Spanish. That's why we need to know, on what occasions we should use B and at what times we should use V.
