The verb predicate means, among other things, "to found or base." Despite being attested as early as 1754, that sense has endured attack as a misuse on the grounds that it is not true to its Latin root praedicare, meaning "to proclaim, assert." This criticism, however, has subsided. Predicate can also mean "imply," but be careful about using it to mean "predict"-that use does appear in published sources sometimes, but it's an easy target for usage commentators, who are bound to consider it an all-too-predictable error. The meaning of predicate directly tapped from its Latin root-that is, "to assert"-most often occurs in metaphysic contemplation. A simplistic example of such use is the statement "if y is said to be x (e.g., an apple is a fruit), everything that is predicated of y is predicated of x."
