In this thesis, an analysis is done to test new optimality scores to estimate if they explain better text optimality than mean word length. To do so, some large parallel corpora will be analyzed with 460 languages, 34 unique writing systems, and 54 unique language families to test if these scores explain better text optimality. Also, a study to determine whether language family or writing system best explains the optimality of a language has been done. It concludes with a classification of the writing systems and language families with the scores proposed.
