History of The Arabic Alphabet - Early Islamic Changes

Early Islamic Changes

The Arabic alphabet is first attested in its classical form in the 7th century. See PERF 558 for the first surviving Islamic Arabic writing.

In the 7th century, probably in the early years of Islam while writing down the Qur'an, scribes realized that working out which of the ambiguous letters a particular letter was from context was laborious and not always possible, so a proper remedy was required. Writings in the Nabataean and Syriac alphabets already had sporadic examples of dots being used to distinguish letters which had become identical, for example as in the table on the right. By analogy with this, a system of dots was added to the Arabic alphabet to make enough different letters for Classical Arabic's 28 phonemes. Sometimes the resulting new letters were put in alphabetical order after their un-dotted originals, and sometimes at the end.

The first surviving document that definitely uses these dots is also the first surviving Arabic papyrus (PERF 558), dated April, 643. The dots did not become obligatory until much later. Important texts like the Qur'an were frequently memorized; this practice, which survives even today, probably arose partly to avoid the great ambiguity of the script, and partly due to the scarcity of books in times when printing was unheard-of in the area and every copy of every book had to be written by hand.

The alphabet then had 28 letters, and so could be used to write the numbers 1 to 10, then 20 to 100, then 200 to 900, then 1000 (see Abjad numerals). In this numerical order, the new letters were put at the end of the alphabet. This produced this order: alif (1), b (2), j (3), d (4), h (5), w (6), z (7), H (8), T (9), y (10), k (20), l (30), m (40), n (50), s (60), ayn (70), f (80), S (90), q (100), r (200), sh (300), t (400), th (500), dh (600), kh (700), D (800), Z (900), gh (1000).

The lack of vowel signs in Arabic writing created more ambiguities: for example, in Classical Arabic ktb could be kataba = "he wrote", kutiba = "it was written" or kutub="books". Later, vowel signs and hamzas were added, beginning some time in the last half of the 6th century, at about the same time as the first invention of Syriac and Hebrew vocalization. Initially, this was done using a system of red dots, said to have been commissioned by an Umayyad governor of Iraq, Hajjaj ibn Yusuf: a dot above = a, a dot below = i, a dot on the line = u, and doubled dots giving tanwin. However, this was cumbersome and easily confusable with the letter-distinguishing dots, so about 100 years later, the modern system was adopted. The system was finalized around 786 by al-Farahidi.

Before the historical decree by Hajjaj ibn Yusuf, all administrative texts were recorded by Persian scribes in Middle Persian language using Pahlavi script, but many of the initial orthographic alterations to the Arabic alphabet might have been proposed and implemented by the same scribes.

When new signs were added to the Arabic alphabet, they took the alphabetical order value of the letter which they were an alternative for: tā' marbūta (see also below) took the value of ordinary t, and not of h. In the same way, the many diacritics do not have any value: for example, a doubled consonant indicated by shadda does not count as a letter separate from the single one.

Some features of the Arabic alphabet arose because of differences between Qur'anic spelling (which followed the Meccan dialect pronunciation used by Muhammad and his first followers) and the standard Classical Arabic. These include:

• tā' marbūta: This arose because the -at ending of feminine nouns (tā' marbūta) was often pronounced as -ah and written as h. To avoid altering Quranic spelling, the dots of t were written over the h.
• y (alif maksura ى) used to spell ā at the ends of some words: This arose because ā arising from contraction where single y dropped out between vowels was in some dialects pronounced at the ends of words with the tongue further forward than for other ā vowels, and as a result in the Qu'ran it was written as y.
• ā not written as alif in some words: The Arabic spelling of Allāh was decided before the Arabs started using alif to spell ā. In other cases (for example the first ā in hāðā = "this"), it may be that the Meccan dialect pronounced those vowels short.
• hamza: Originally alif was used to spell the glottal stop. But Meccans did not pronounce the glottal stop, replacing it with w, y or nothing, lengthening an adjacent vowel, or, between vowels, dropping the glottal stop and contracting the vowels, and the Qur'an was written following Meccan pronunciation. The Arabic grammarians invented the hamza diacritic sign and used it to mark the glottal stop. Hamza is Arabic for "hook".
