Liste der archaischen Keilschriftzeichen (German: [ˈlɪstə deːɐ̯ ʔaʁˈçaːɪʃn̩ ˈkaɪlʃʁɪftˌtsaɪçn̩]; "list of archaic cuneiform signs"), abbreviated LAK, is a dictionary of Sumerian cuneiform signs of the Fara period (Early Dynastic IIIa, c. 25th century BC short chronology, 26th century BC middle chronology),[2] published in 1922 by German sumerologist and theologian P. Anton Deimel (1865–1954).
The list enumerates 870 distinct cuneiform signs.
The sign inventory in the archaic period was considerably larger than the standard inventory of the later Akkadian (2350 to 2100) or Neo-Sumerian (Ur III) (21st century; all dates short chronology) periods.
If it is necessary to identify the pre-classical sign intended, its LAK number is customarily given, in the form of LAK-1 to LAK-870.
Deimel also published a Sumerian dictionary (Šumerisches Lexikon) in 1928.
