Fluency and understanding are strongly related to each other. (Hudson, Lane, 2005) Therefore, students who read fluently can be "free from word identification problems that may hinder comprehension." Fluent reading is closely related to correct expression because we are more likely to express a word by reading it fluently. Accuracy is a key component of fluency. Accuracy is the ability to read by recognizing words automatically without errors. (Rasinski, 2003). In reality, fluidity is an integral part of precision. To reach the fluency stage, the reader must first achieve a level of reading accuracy. Reading accurately means reading automatically without errors. For the reader to reach this stage, he must constantly practice reading, especially by repeating words he does not know. Repetition helps the reader to memorize and pronounce the word correctly, helping him to read it correctly automatically, and then reach the fluency phase. Historically, the conditions of the emergence of this standard could be linked to the early efforts of academic works from psychological, philosophical and sociological perspectives. A function of this standard could be linked
