Predicate rap time
Are you ready?
Here, let's go!
A predicate is one of the two main parts of a sentence
The other being the subject
Which the predicate modifies
For the simple sentence John is yellow
John acts as the subject
And is yellow acts as the predicate
A subsequent description of the subject
Headed with a verb

In current linguistic semantics
A predicate is an expression
That can be true of something
Thus, the expressions "is yellow"
Or "is like broccoli"
Are true of those things
That are yellow or like broccoli respectively
This notion is closely related to the notion
Of a predicate in formal logic
Which includes more expressions
Than the covered one
