The supersyllabogram AKA in Linear A = either wine skin or an embossed cup:
BOLD: n. e.g. 1. A = a supersyllabogram for which the definition is either certain or highly probable.
Italics: n. e.g. 7. KI = a supersyllabogram for which the definition is possible.
Standard font: n. e.g. 2 = a supersyllabogram for which the definition is unlikely or questionable.
It is almost certain that the supersyllabogram A in Linear A means either a wine skin or an embossed cup.
1. A aka = aska = a0ska = wine skin -or- apero PGS a1mpeloj = a vine Cf. Linear B apero -or- aresana NM1 a1leisana <- a1leison = an embossed cup (arch. acc.) = de/paj (Homeric) Cf. Linear B dipa/arisu NM1 a1leisu <- a1leison = embossed cup
Note that it appears on HT 2 (Haghia Triada) dealing with olive oil, which is sometimes served from a vessel and on the other 3 tablets, same provenance, all of which deal with vessels, hence the reading, embossed cup:
HT 2 oo HT 39 ve KH 83 ve MA 10 ve
oo = olive oil
ve = vessels
