Eulogia

Blessing — also the blessed (but not consecrated) bread distributed in certain contexts as a sign of ecclesial unity.

Eulogia (blessing, from eu, well, and logos, word) is both the general term for a blessing and the specific term for blessed but not consecrated bread given as a sign of communion. In the early Church, eulogia was sent from one bishop to another as a sign of full communion: receiving and eating the eulogia of another church meant being in communion with it. The breaking of communion was expressed by refusing or returning the eulogia. Today eulogia refers to blessed bread in various contexts, including the antidoron distributed after the Liturgy.
