Sentence structure

Grade 6 · English Language Arts · Free lesson

Hi there! I am Studyfin, your ELA tutor. Today, we will explore how to build and edit complete sentences!

Every complete sentence needs two main parts to express a whole thought. First, it needs a subject, which is the person or thing doing the action. Second, it needs a predicate, which is the action itself.

When we edit our drafts, we must look out for run-on sentences. A run-on happens when two complete thoughts are pushed together without the right punctuation to separate them.

The Run-On Collision! Thought 1: I ran Thought 2: I fell Oops! No stop sign or connector!

To fix a run-on, we edit our work. We can add a period to make two separate sentences. Or, we can use a comma and a joining word like 'and', 'but', or 'so' to link them safely.

The Safe Connection I ran , and I won! Perfect! Edited with a comma and a conjunction.
✏️ Worked example

Let us practice editing a draft. Read this run-on sentence: 'The puppy barked at the mail carrier he wagged his tail.' How can we fix this to make it grammatically correct?

  1. Identify the first complete thought (subject and predicate): 'The puppy barked at the mail carrier.'
  2. Identify the second complete thought (subject and predicate): 'He wagged his tail.'
  3. Notice that they are pushed together with no punctuation or connecting words in between.
  4. Choose a way to fix it. Let us use a period to separate them into two clean, clear sentences.
  5. Write the final edited version: 'The puppy barked at the mail carrier. He wagged his tail.'
