Wikipedia Wrote:"By 2700 BCE the ancient Egyptians had developed a set of some 22 hieroglyphs to represent the individual consonants of their language, plus a 23rd that seems to have represented word-initial or word-final vowels. These glyphs were used as pronunciation guides for logograms, to write grammatical inflections, and, later, to transcribe loan words and foreign names. However, although alphabetic in nature, the system was not used for purely alphabetic writing except when transcribing foreign names. That is, while capable of being used as an alphabet, it was in fact nearly always used with a strong logographic component, presumably due to strong cultural attachment to the complex Egyptian script."

Wikipedia Wrote:"Hittite orthography was directly adapted from Old Assyrian cuneiform. The HZL of Rüster and Neu lists 375 cuneiform signs used in Hittite documents (11 of them only appearing in Hurrian and Hattic glosses), compared to some 600 signs in use in Old Assyrian. About half of the signs have syllabic values, the remaining are used as ideograms or logograms to represent the entire word -- much as the characters "$", "%" and "&" are used in contemporary English.

Cuneiform signs can be employed in three functions: syllabograms, Akkadograms or Sumerograms. Syllabograms are characters that represent a syllable. Akkadograms and Sumerograms are ideograms originally from the earlier Akkadian or Sumerian orthography respectively, but not intended to be pronounced as in the original language; Sumerograms are mostly ideograms and determiners."
