It spells sa inside a word.
Linear B palace records include clay inventories and accounts of goods and people. The sign supplied one syllable within a word. Linear B adapted Linear A, an earlier Cretan script; Crete also used Cretan Hieroglyphic. The earliest Linear B records are from Knossos around 1450 BCE.
