Linear A ideograms 620

These are the most common Linear A ideograms for livestock, crops, olives, barley and wheat. Unlike Mycenaean Linear B, Linear draws a distinction between certain species of wheat, with the ideogram for “wheat” accompanied by the supersyllabogram DI meaning dideru = “roasted einkorn” and the same ideogram accompanied by QE , signifying qerie = “emmer wheat”, while at the same time using a slightly different ideogram for “barley”.  In addition, the word sara2 (sarai) = “sharia wheat”. All of these words are firmly established and confirmed in either the Old Minoan or the pre-Greek substratum. Most of the Linear A ideograms are either very similar or identical to their Linear B counterparts.
