For example the spelling <C U L8R> (rather than <see you later>), uses <C> and <U> as morphograms, <L> as a phonogram, <R> as a syllabogram, and <8> as 'rhymogram'.
Third, we need to provide a model that can account for the use of graphemes at higher phonological levels, to see how syllabograms and morphograms can be intermingled with the default phonograms of standard spelling.
In a work where palaeographic arguments abound, it would seem appropriate that the authors collectively ask themselves whether it is likely in terms of internal, structural features of the script (e.g., use and choice of syllabograms), external aspects (e.g., sign forms, wedge sequence, etc.), accounting procedures, and other evidence that there are really three hundred years between Urukagina and the high point of Ur III.
It contains excellent palaeographic studies, tables of syllabograms, and catalogues of Fara-period texts (correlated where possible with their archaeological find spots), bibliographies to individual tablets, and much more.
