Why was the Greek alphabet a significant development?

Greek alphabet, writing system that was developed in Greece about 1000 bce. It is the direct or indirect ancestor of all modern European alphabets. Derived from the North Semitic alphabet via that of the Phoenicians, the Greek alphabet was modified to make it more efficient and accurate for writing a non-Semitic language by the addition of several new letters and the modification or dropping of several others. Most important, some of the symbols of the Semitic alphabet, which represented only consonants, were made to represent vowels: the Semitic consonants ʾalef, he, yod, ʿayin, and vav became the Greek letters alpha, epsilon, iota, omicron, and upsilon, representing the vowels a, e, i, o, and u, respectively. The addition of symbols for the vowel sounds greatly increased the accuracy and legibility of the writing system for non-Semitic languages.

Before the 5th century bce the Greek alphabet could be divided into two principal branches: the Ionic (eastern) and the Chalcidian (western). Differences between the two branches were minor. The Chalcidian alphabet probably gave rise to the Etruscan alphabet of Italy in the 8th century bce and hence indirectly to the other Italic alphabets, including the Latin alphabet, which is now used for most European languages. In 403 bce, however, Athens officially adopted the Ionic alphabet as written in Miletus, and in the next 50 years almost all local Greek alphabets, including the Chalcidian, were replaced by the Ionic script, which thus became the Classical Greek alphabet.

The early Greek alphabet was written, like its Semitic forebears, from right to left. This gradually gave way to the boustrophedon style, and after 500 bce Greek was always written from left to right. The Classical alphabet had 24 letters, 7 of which were vowels, and consisted of capital letters, ideal for monuments and inscriptions. From it were derived three scripts better suited to handwriting: uncial, which was essentially the Classical capitals adapted to writing with pen on paper and similar to hand printing, and cursive and minuscule, which were running scripts similar to modern handwriting forms, with joined letters and considerable modification in letter shape. Uncial went out of use in the 9th century ce, and minuscule, which replaced it, developed into the modern Greek handwriting form.
