Oblation is the act of making a religious offering or something offered in an act of worship or devotion. It can also, more specifically, be used to mean the presentation of bread and wine to God in the Eucharist, the Christian service commemorating the Last Supper.
The noun oblation has its origins in Latin, being derived from offerre, "to offer." Its usual context is religious or church services. The adjectival forms are "oblational" and "oblatory," but there is no corresponding verb. There is a separate and unrelated adjective, oblate, which is used to describe something that is flattened or depressed at the poles.
