Phonology comes from the Greek word phono and the word logos. Phono means sound or sound, and the emblem implies science. Phonology is divided into 2 (two), namely phonetics and phonemes. Phonetics is the science of sound that talks explicitly about sound problems without paying attention to the function and meaning of sound. Phonemes are the study of sounds that study parts of the little unity of a language. Vowels in Arabic phonemes are commonly called crazy. Vowel types are the vowel phoneme Fathah, the vowel phoneme Kasrah, and the vowel phoneme Dhommah. A voice or vowel is a language sound that comes from the vibration of a person's throat vocal cords. The difference in the variety of sounds is the long and short verbal aspects.
