👉 Rechain, in French, is a type of writing system used primarily in France. It was developed by Jean de La Fontaine and was introduced into Europe during the 16th century. The rechain consists of two lines for each word, with the first line indicating the number of syllables in the word, and the second line containing the consonants and vowels that make up the word. Rechains are used primarily to write short texts such as letters or diary entries.
