 3.  Lesson 1 of 10

A sentence is a group of words that shares a complete thought. Learning to find 
its main parts gives you a useful starting point for all the grammar in this course.
In this lesson, you will look for who or what a sentence is about and what that 
subject does or is.

## Find the subject and the verb

### The subject tells who or what

The subject is the person, animal, place, thing, or idea that the sentence is about.
Ask who or what before the action to help find it. In _The small dog barked_, the
sentence is about the dog, so _dog_ is the subject. The word _small_ gives more 
information about the dog, but it is not the main subject.

### The verb tells an action or a state

A verb can tell what someone or something does, such as _run_, _think_, or _write_.
It can also tell what someone or something is or feels, as in _is_, _seems_, or 
_feels_. In _The soup is warm_, _soup_ is the subject and _is_ is the verb. A sentence
can have extra words, but the subject and verb are a helpful core.

Try reading a sentence and asking two questions: Who or what is this about? What
does that person or thing do, or what is true about it? For example, in _Our class
reads a story_, the class is the subject and reads is the verb. In _The windows 
are open_, windows is the subject and are is the verb.

## Make a complete thought

### A sentence needs enough information

A complete sentence usually tells us a subject and a verb, and it makes sense as
a whole thought. _Birds sing_ is complete: it tells us who and what they do. _My
friend_ is not a complete sentence by itself because we do not know what the friend
does or what is true about the friend. _Ran down the path_ is also incomplete if
we do not know who ran.

### Notice sentence fragments

A fragment is a word group that looks like a sentence but leaves out an important
part. A heading such as _After the game_ can be useful in a note, but it does not
tell a complete thought. You can complete it by adding a subject and verb: _After
the game, we went home._ A fragment can also be fixed by adding a missing subject:
_The team cheered after the game._

When you are unsure, read the words aloud. Ask whether a listener would know who
or what you mean and what happened. Some short sentences have an understood subject
in conversation, such as _Stop!_ The person being spoken to is understood. In school
writing, practise making the subject clear unless the instruction is meant to be
short.

## Put words in a clear order

### Start with a simple pattern

Many English sentences use this pattern: subject, verb, then other information. 
For example, _Maya draws a flower._ Maya is the subject, draws is the verb, and 
a flower tells what she draws. The sentence _A flower Maya draws_ is harder to understand
because the familiar order has changed. Grammar helps readers see how the words 
connect.

### Add details without losing the core

You can add details before or after the core sentence. _Maya draws a flower_ can
become _Maya draws a bright flower in her notebook._ The subject is still Maya and
the verb is still draws. The detail words tell what the flower is like and where
she draws it. If a sentence becomes long, check that its subject and verb still 
match and that the main idea remains easy to find.

Here is another example: _On Saturday, the children played outside._ The opening
phrase tells when. The subject is children, and the verb is played. Keep the core
in mind when you add information: details can make writing vivid, but the sentence
still needs to express a complete thought.

## Key takeaways

 * The subject tells who or what a sentence is about.
 * The verb tells an action or a state.
 * A complete sentence expresses a complete thought.
 * Simple subject, verb, and detail order is often easiest to follow.

## Practice

Write three complete sentences about a familiar activity. Underline the subject 
in each sentence and circle the verb. Then choose one fragment, such as _After lunch_,
and turn it into a complete sentence by adding a subject and a verb.
