Trying to Understand Phrases vs Clauses While Editing My English Essay

Question

I'm editing my English essay and I keep getting confused about when something is a phrase or a clause. For example, in my draft I have sentences like, "Before the sun rises, I go for a run" and "Running in the park every morning helps me relax."

My teacher commented that I should pay attention to the difference between phrases and clauses to improve my writing, but I'm not sure I really get how to tell them apart. Can anyone explain with these examples or share some more?

Context:
I'm preparing for an academic writing course (ESL learner, American English).

To clearly distinguish between phrases and clauses, let's use the core pattern: A clause has a subject and a verb; a phrase does not have both.

Examples:

Clause: "After I finish my homework" ("I" is the subject; "finish" is the verb)
Phrase: "After finishing my homework" (no subject performing the action; "finishing" is a verb form but not the main verb)

Another Pair:

Clause: "While she was reading, the phone rang."
Phrase: "While reading, the phone rang."

The first “while” group has a subject (“she”) and a verb (“was reading”); the second does not, so it’s a phrase.

Practice:

Spot if your sentence has both a subject and a verb in the introductory part. If yes, it's a clause. If not, it's a phrase.

Self-edit tip:
Look for pieces like “before leaving,” “because it rained,” or “since she left.” Ask: is there a full subject-verb pair here? If not, revise for clarity.

Understanding the difference often becomes clearer through direct comparison. Clauses always have both a subject and a verb; phrases do not.

Compare these examples:

"Because Maria studied late, she passed the exam." (Clause: "Because Maria studied late" — subject = Maria, verb = studied)
"Studying late at night, Maria passed the exam." (Phrase: "Studying late at night" — no subject, participle only)

Another pair:

"When the bell rings, the students leave." (Clause: "When the bell rings")
"Ringing the bell, the students left." (Phrase: "Ringing the bell")

Practice Suggestion:
Highlight the intro parts in your own writing and label S(subject) and V(verb). If you can’t find both, it’s a phrase.

Corrective feedback:
Try rewriting phrases into full clauses for academic clarity. This will help you use complex sentences confidently.

Nora Grammar · Answer

You can use a simple check-list to tell a phrase from a clause:

Look for a subject (who or what is doing something?)
Look for a verb that's acting as the main action (not just a participle or infinitive).

Real examples:

"If the weather improves, we will play outside." ("If the weather improves" — has both subject and verb: clause)
"To play outside, we need good weather." ("To play outside" — verb form only: phrase)

Contextual practice:
Go through your essay and circle the first group of words in each sentence. Does that group have a subject and a main verb? Mark it as a clause. If not, it's a phrase.

Correction tip:
If a phrase is unclear or confusing, consider expanding it into a clause for more formal academic writing.
