The letter "و" is the twenty-seventh letter of the Arabic alphabet. It is pronounced as "waw" and represents the sound /w/. In Arabic script, it is written as a single character and can connect to other letters when forming words. In addition to being a consonant, "و" also serves as a conjunction meaning "and." It is commonly used to link words and phrases in sentences, similar to its English counterpart. This dual function makes "و" an essential component of Arabic grammar and writing.
