Cuneiform times of Parthian Empire (250 BC – AD 226). The last known cuneiform inscription, an astronomical text, was written in 75 AD. The complexity of the system prompted the development of a number of simplified versions of the script. Old Persian was written in a subset of simplified cuneiform characters known today as Old Persian cuneiform. It formed a semi-alphabetic syllabary, using far fewer wedge strokes than Assyrian used, together with a handful of logograms for frequently occurring words like "god" and "king". Ugaritic was written using the Ugaritic alphabet, a standard Semitic style alphabet (an "abjad") written using the
Ka (cuneiform) Ka (cuneiform) The cuneiform ka sign is a common, multi-use sign, a syllabic for "ka", and an alphabetic sign used for "k", or "a"; it is common in both the "Epic of Gilgamesh" over hundreds of years, and the 1350 BC Amarna letters. Cuneiform "ka" is nearly identical to a similar 'mid-size' to larger cuneiform sign, ša (cuneiform); because both "ka", and "ša" have two separate specific uses, once these usage sites are identified on a specific Amarna letter, for example, the difference between the two can be followed. Cuneiform "ka" has a secondary use as the pronoun suffix, "-yours".
