Here are some examples:
* "Running" (This implies someone is running, but doesn't say who)
* "Sleeping" (This implies someone is sleeping, but doesn't say who)
* "Eating" (This implies someone is eating, but doesn't say who)
* "To be happy" (This implies someone is in a state of happiness, but doesn't say who)
Bare predicates are often used in:
* Infinitive phrases: "To be or not to be"
* Imperative sentences: "Run!"
* Participial phrases: "Running down the street, he tripped."
* Clauses with a suppressed subject: "It is important to be kind." (The implied subject is "one" or "people")
In contrast, a complete predicate includes a subject:
* "The dog is running." (Subject: "The dog", Predicate: "is running")
