Notes on Complete vs Incomplete Sentences

Definition of a sentence
- A sentence is a group of words that expresses a complete thought.
- It has a subject and a verb.
- It is an independent clause and can stand on its own.
Incomplete sentences (fragments)
- Do not express a complete thought.
- May be missing a subject or a verb.
- May be a dependent clause or a dependent phrase.
- Cannot stand on their own as a complete sentence.
Concrete example from transcript
- The sentence: I am.
- This is presented as a complete sentence with a subject (I) and a verb (am).
- It expresses a complete thought (existence: “I am”).
- The idea of existential completeness is acknowledged: even a short form can be complete if it has a subject and a verb and expresses a full thought.
The role of dependent clauses in creating fragments
- When a dependent word or conjunction appears at the start, the initial fragment becomes incomplete until it is joined with an independent clause.
- Example:
- Fragment: When I am
- Subordinating conjunction: when
Key takeaway for editing
- To revise sentences, identify the subject and the verb.
- Check if the sentence can stand alone as an independent clause.
- If not, identify the dependent clause and attach it to an appropriate independent clause to form a complete sentence.
- The goal is to avoid leaving readers hanging.

Independent clause
- Definition: Can stand alone as a complete sentence.
- Contains a subject and a verb.
- Expresses a complete thought.
Dependent clause
- Definition: Cannot stand alone as a complete sentence.
- Begins with a subordinating conjunction or a dependent marker.
- Depends on an independent clause to form a complete sentence.
How fragments become complete sentences
- By attaching a dependent clause to an appropriate independent clause.
- Example from transcript:
- Dependent clause: When I am 64
- Attempted independent clause base: I will dye my hair purple
- Completed sentence: When I am 64, I will dye my hair purple
Important note on the example’s phrasing
- The transcript asks: what is the independent clause after adding the dependent piece?
- It states: “I will dye” as the independent clause, but standard grammar identifies the full independent clause as: “I will dye my hair purple.”
- The dependent clause is still: “When I am 64.”
- The combined, correct complete sentence is: “When I am 64, I will dye my hair purple.”
Practical implication
- Always ensure the independent clause expresses a complete thought and can stand alone after a dependent clause is attached.

What is a subordinating conjunction?
- A word that introduces a dependent clause and makes it reliant on an independent clause.
Examples mentioned in transcript
- when (example provided)
- because
- although
- however
- while
- after
- and so on
Function in sentence structure
- They start dependent clauses that cannot stand alone.
- They signal relationships such as time, cause, contrast, condition, and concession.
Practical use
- Recognize when a sentence begins with a subordinating conjunction to identify the dependent clause.
- Decide which independent clause will complete the thought.

Complete sentence example
- “I am.”
- Subject: I
- Verb: am
- Complete thought: yes
Fragment/dependent example
- “When I am”
- Fragment: dependent clause without an independent clause
Complete sentence by attachment
- “When I am 64, I will dye my hair purple.”
- Analysis per transcript:
- Dependent clause: When I am 64
- Independent clause (as the main clause): I will dye my hair purple
- Full sentence is complete when both parts are connected
Note on terminology
- The transcript uses “I will dye” as the potential independent part, but the conventional independent clause is the full phrase: “I will dye my hair purple.”

Step 1: Locate the subject and the verb in the sentence.
Step 2: Determine whether the sentence can stand alone as a complete thought.
Step 3: If not complete, identify the dependent clause (often introduced by a subordinating conjunction like when, because, although, etc.).
Step 4: Attach the dependent clause to an appropriate independent clause to form a complete sentence.
Step 5: Check for smoothness and clarity; ensure punctuation supports the structure (e.g., a comma separating a dependent clause from the independent clause when the dependent clause comes first).
Step 6: Confirm there are no unresolved fragments that leave readers hanging.

Writing clarity: Ensures readers understand the complete thought without ambiguity.
Academic editing: Fragments can undermine formality; identifying dependent clauses helps in revising for standard prose.
Creative writing: Fragments can be stylistically intentional, but this transcript focuses on standard grammar where fragments are generally avoided in formal contexts.
Language learning: Recognizing independent vs dependent clauses helps learners construct grammatically correct sentences and interpret complex sentences.

Prompt 1: Identify the independent and dependent parts of the sentence: "When I am 64, I will dye my hair purple."
- Dependent: When I am 64
- Independent: I will dye my hair purple
Prompt 2: Determine whether the following is a complete sentence or fragment: "Because I forgot".
- Fragment (needs an independent clause to complete: e.g., "Because I forgot, I was late.")
Prompt 3: Rewrite the fragment to form a complete sentence: "When I am 64" + "I will dye my hair purple".
- Complete sentence: "When I am 64, I will dye my hair purple."
Prompt 4: Identify the subordinating conjunctions in the following: "While you were sleeping, the cat jumped on the bed."
- Subordinating conjunction: While

A complete sentence must have:
- A subject
- A verb
- The ability to express a complete thought (independent clause)
A fragment (incomplete sentence) lacks one of the above, typically a dependent clause introduced by a subordinating conjunction (e.g., when, because, although, while, after, etc.).
To fix fragments, attach the dependent clause to an appropriate independent clause to form a complete sentence.
Punctuation and word order matter: place the comma correctly when a dependent clause comes before the independent clause (e.g., When I am 64, I will dye my hair purple).
Always verify whether the identified independent clause can stand alone as a complete thought; if not, revise accordingly.

The core skill demonstrated in the transcript is the ability to isolate the independent clause in a sentence that includes a dependent clause and to ensure cohesion by attaching the dependent clause to an appropriate independent clause so that readers are not left hanging.
