History
י, yod, is the tenth letter of the Hebrew alphabet. It stands for the y of English yes,[1] and it also serves as a vowel letter for the vowels hireq, sere and segol.[2] Ashkenazi Jews often call it yud, the name the letter has in Yiddish.[3] The name goes back to an Egyptian hieroglyph of a hand; compare the Hebrew word yad, hand.[4]
In gematria yod is ten,[5] and two yods in a row stand for the name of God.[6] Its small size is proverbial. In Modern Hebrew the tip of the yod is something small and insignificant,[7] and someone who worries about it is picky about minor details.[8] It is also the jod of Matthew's Gospel, one jod or one tittle, and scribes often overlooked it because of its size.[9]
In grammar, yod at the front of a verb marks the third person masculine singular of the future tense: from m-l-k, king, comes yimlokh, he will reign.[10] At the end of a noun it means my: av, father, becomes avi, my father.[11]
In Yiddish, a single yud can be the vowel /i/ or the consonant /j/, and where the two meet a dot below marks the vowel, so the word Yidish is spelled ייִדיש.[12] Two yuds together, יי, spell the diphthong /ej/.[13]
The Phoenician letter behind yod also gave rise to the Greek iota,[14] and through it to Latin I and J and to Cyrillic І,[15] the dotted і that the Soviet spelling reform removed from Russian.[16]
