In all its stages, the morphology of Greek shows an extensive set of productive derivational affixes, a limited but productive system of compounding and a rich inflectional system. Although its morphological categories have been fairly stable over time, morphological changes are present throughout, particularly in the nominal and verbal systems. The major change in the nominal morphology since the classical stage was the disuse of the dative case (its functions being largely taken over by the genitive). The verbal system has lost the infinitive, the synthetically-formed future and perfect tenses and the optative mood. Many have been replaced by periphrastic (analytical) forms.
In addition to the letters, the Greek alphabet features a number of diacritical signs: three different accent marks (acute, grave, and circumflex), originally denoting different shapes of pitch accent on the stressed vowel; the so-called breathing marks (rough and smooth breathing), originally used to signal presence or absence of word-initial /h/; and the diaeresis, used to mark full syllabic value of a vowel that would otherwise be read as part of a diphthong. These marks were introduced during the course of the Hellenistic period. Actual usage of the grave in handwriting saw a rapid decline in favor of uniform usage of the acute during the late 20th century, and it has only been retained in typography.
After the writing reform of 1982, most diacritics are no longer used. Since then, Greek has been written mostly in the simplified monotonic orthography (or monotonic system), which employs only the acute accent and the diaeresis. The traditional system, now called the polytonic orthography (or polytonic system), is still used internationally for the writing of Ancient Greek.
The oldest description of the creation of a golem by a historical figure is included in a tradition connected to Rabbi Eliyahu of Chem (15501583).
A Polish Kabbalist, writing in about 16301650, reported the creation of a golem by Rabbi Eliyahu thus: "And I have heard, in a certain and explicit way, from several respectable persons that one man [living] close to our time, whose name is R. Eliyahu, the master of the name, who made a creature out of matter [Heb. Golem] and form [Heb. tzurah] and it performed hard work for him, for a long period, and the name of emet was hanging upon his neck, until he finally removed it for a certain reason, the name from his neck and it turned to dust." A similar account was reported by a Christian author, Christoph Arnold, in 1674.
Rabbi Jacob Emden (d. 1776) elaborated on the story in a book published in 1748:
"As an aside, I'll mention here what I heard from my father's holy mouth regarding the Golem created by his ancestor, the Gaon R. Eliyahu Ba'al Shem of blessed memory. When the Gaon saw that the Golem was growing larger and larger, he feared that the Golem would destroy the universe. He then removed the Holy Name that was embedded on his forehead, thus causing him to disintegrate and return to dust. Nonetheless, while he was engaged in extracting the Holy Name from him, the Golem injured him, scarring him on the face."
According to the Polish Kabbalist, "the legend was known to several persons, thus allowing us to speculate that the legend had indeed circulated for some time before it was committed to writing and, consequently, we may assume that its origins are to be traced to the generation immediately following the death of R. Eliyahu, if not earlier."
