In grammar, the predicate is the main verb and all the words and phrases and clauses that go with it.

Scroll down a bit and read the noun definitions.

The predicator -- "n. - An expression that designates a property or relation"

This could be a noun phrase or clause, an adjective or adj phrase or adj clause, etc.

Predication has to do with making sure your sentence is clear and logical.
