The letter "ر" is the Arabic letter that represents the sound /r/. It is the tenth letter in the Arabic alphabet and is pronounced similarly to the English "r," but with a slight roll of the tongue. In Arabic script, "ر" is written in a simple form and does not connect to the following letter when it appears at the beginning or end of a word. In terms of numerical value, "ر" corresponds to the number 200 in the Arabic numeral system. This letter is commonly found in many Arabic words, such as رجل (rajul), meaning "man," and رسم (rasm), meaning "drawing." Its distinct sound and shape make it an essential part of the Arabic language.
