Not sure where you are getting your information on the Greek language. I have 6 Lexicons, 7 Grammars, and 4 Reference works and none of them suggest the nuance in meaning for the forms of the Greek words you are citing. They mean 'true, genuine' ... nothing more or less.

do you accept the Greek Orthodox Church understands the Greek language? If yes, look up what they believe about the Eucharist.

Vine’s Expository dictionary of New Testament Words:

“Note: “Alethinos is related to alethes as form to contents or substances; alethes denotes the reality of the thing, alethinos defines the relation of the conception to the thing to which it corresponds = genuine” (Cremer).”

But lest you think I am pinning everything on one obscure note in one Greek dictionary, I’d like to point out the absolute mountain of historical evidence on this one. The Church Fathers and indeed the Greek Orthodox Church for 2000 years all held solidly to the doctrine of the Real Presence—and the opposite view was always roundly condemned.

Here’s another lengthy discussion as well, complete with etymological and other cognate citations:

“Alethes lays bare what is not true and not real; alethinos lays bare what is incongruous with the concept in question. The standard applied by alethes is reality; by alethinos it is the concept. In alethes the concept is congruous with the matter at hand; in alethinos the matter at hand is congruous with the concept.”
