 #### Predicate

In English, it contains a verb and usually also an object. (See [Verbs](../figs-verbs/01.md).) (In some languages, the predicate refers only to the object and does not contain a verb.) In the sentences below, the subjects are “the man” and “he.” The predicates are in bold.

 #### Clauses
 
-Sentences can also have clauses and other phrases. Clauses are like sentences because they have a subject and a predicate, but they do not normally occur by themselves. Here are some examples of clauses. The subjects are in bold, and the predicates are bolded.
+Sentences can also have clauses and other phrases. Clauses are like sentences because they have a subject and a predicate, but usually they cannot occur by themselves. Here are some examples of clauses. They cannot occur by themselves because they each start with a word that makes them **dependent** on another sentence. The words that turn the following sentences into **dependent clauses** are in bold.
 
-* when **the maize** **was ready**
+* **when** the maize was ready
-* after **she** **picked it**
+* **after** she picked it
-* because **it** **tasted so good**
+* **because** it tasted so good
 
 Sentences can have many clauses, and so they can become long and complex. But each sentence has to have at least one **independent clause**, that is, a clause that can be a sentence all by itself. The other clauses that cannot be sentences by themselves are called the **dependent clauses**. Dependent clauses depend on the independent clause to complete their meaning. The dependent clauses are bolded in the sentences below.
