The Collaborative International Dictionary of English v.0.48:
Predicate \Pred"i*cate\, v. t. [imp. & p. p. Predicated; p.
pr. & vb. n. Predicating.] [L. praedicatus, p. p. of
praedicare to cry in public, to proclaim. See Preach.]
1. To assert to belong to something; to affirm (one thing of
another); as, to predicate whiteness of snow.
2. To found; to base. [U.S.]
Note: Predicate is sometimes used in the United States for
found or base; as, to predicate an argument on certain
principles; to predicate a statement on information
received. Predicate is a term in logic, and used only
in a single case, namely, when we affirm one thing of
another. "Similitude is not predicated of essences or
substances, but of figures and qualities only."
