?ayyuj, Judah ben David
?AYYUJ, JUDAH BEN DAVID
?AYYUJ, JUDAH BEN DAVID (c. 945–c. 1000), the most important Hebrew grammarian towards the turn of the 10th century. About his life little is known. He was born in Fez and arrived at Córdoba in 960 when the dispute between *Menahem b. Jacob ibn Saruq and *Dunash b. Labrat was at its height. It is doubtful whether he should be identified with Judah b. David, one of the three students of Menahem who composed Teshuvot al Dunash ben Labrat, the two others being Isaac ibn Kapron and Isaac ibn *Gikatilla (ed. by Z. Stern in 1870).
His works include (1) Kit?b al-Tanq?? or Kit?b al-Nuqat ("Book of Vocalization") was translated into Hebrew by Abraham Ibn Ezra. It includes grammatical and masoretic matters, dealing mainly with nouns. (2) Kit?b al-'Af '?l Dhaw?t ?ur?f al-L?n ("The Book of Weak Letter Verbs"), translated into Hebrew by Moses ha-Kohen ibn Gikatilla, by Ibn Ezra, and by Isaac b. Eliezer ha-Levi (1458); parts of an anonymous translation have been found. (3) Kit?b al-'Af '?l Dhaw?t al-Mithlayn ("The Book of Geminate Verbs"), translated into Hebrew by Moses ha-Kohen ibn Gikatilla and Ibn Ezra (entitled Po'ole ha-Kefel).
(4) Kit?b al-Nutaf ("Book of Plucked Feathers"); Ibn Ezra called the book Sefer ha-Kora?ah ("Book of Baldness"), and this later became corrupted to Sefer ha-Rok?ah. In this book he intended to explain the difficult verses in the eight books of the Prophets by linguistic method. There are extant parts on Joshua, Judges, Kings, Isaiah, Jeremiah, and Ezekiel, which include discussions of individual words, as well as a discussion on the importance of the meteg and other accents for understanding the Hebrew language.
The originals and the Hebrew translations of (1) (2) and (3) were published by J.L. Dukes (1844), G.W. Nutt (1870), and M. Jastrow (1897). Remnants of the Arabic original of (4) and their translation into modern Hebrew were published by P. Kokovtsov (see bibl.), S. Abramson, I. Eldar, and N. Allony. Recently, all these and other remnants were republished by N. Basal in Kit?b al-Nutaf (2001).
In his two works on the verb, ?ayyuj developed the view that all Hebrew roots are made up of three letters, one of which, however, may be interchanged when conjugated with a weak letter, and may be elided or assimilated to a letter with a dagesh. This is a departure from the earlier view which recognized two-letter roots (?? ,?? ,?? ,??) and even some one-letter roots (the ? and the ? of ??? and ???). According to G. Goldenberg (Leshonenu 44 (1980), 281–292), however, ?ayyuj's major invention was not the tri-literality of the Hebrew verb but rather his concept of s?sin layyin.
His works spread rapidly throughout the Eastern countries and even became popular in Germany. Jonah ibn Jan?a? completed in his Kit?b al-Mustala?aq the material missing in ?ayyuj's works. Based on ?ayyuj's theory, Ibn Jan?a? also wrote a comprehensive biblical Hebrew grammar and lexicon. Moses ha-Kohen ibn Gikatilla (?) prepared a synopsis in Mukhta?ar ?ayyuj (synopsis of ?ayyuj's works); copies of these books were found in the Cairo Genizah. Several works following ?ayyuj's footsteps were written, including Sefer ha-Shoham, by Moses b. ha-Nesi'a, and Sefat Yeter by Isaac b. Eliezer ha-Levi. All the work on Hebrew language and biblical exegesis since ?ayyuj has been based on his ideas, and much of what he said, as well as his terminology (coined later on in Hebrew), is used to this day.
