ASCII Character ו
Hebrew letter VavWaw/Vav (wāw "hook") is the sixth letter of the Semitic abjads, including the Hebrew alphabet. It represents the consonant [w] in classical Hebrew, and [v] in modern Hebrew, as well as the vowels [u] and [o]. In text with niqqud, a dot is added to the left or on top of the letter to indicate, respectively, the two vowel pronunciations. The letter likely originated with an Egyptian hieroglyph which represented the word mace. In Modern Hebrew, the word וָו vav is used to mean both "hook" and the letter's name (the name is also written וי״ו). Vav in gematria represents the number six, and when used at the beginning of Hebrew years, it means 6000 (i.e. ותשנד in numbers would be the date 6754). In modern Hebrew, the frequency of the usage of vav, out of all the letters, is about 10.00%.
