Vary Your Sentence Beginnings: Time, Place and How Openers
Stop starting every sentence the same way. Learn to open with a time, place or how word, add the comma, and keep the meaning clear when you revise.
The idea
Read this aloud: We went to the lake. We set up the tent. We ate lunch. We swam. The facts are fine, but the rhythm is like a drum that only plays one beat. When every sentence starts with the same word, the writing sounds flat.
You can change the beat by moving a detail to the front. Many sentences already tell when something happened, where it happened or how it happened. That detail can open the sentence. Time openers: On Saturday, After lunch, Later, First. Place openers: Beside the picnic tables, At the end of the dock. How openers: Quietly, With a grin, Hungry from the swim.
Use a comma after an opener that is longer than one word or that sets up the sentence: After lunch, we swam. Quietly, she opened the door. A one- or two-word opener can sometimes go without a comma if the sentence still reads clearly, but putting the comma in is always correct, so use it when you are unsure.
Check that the meaning stays the same. Moving words must not change who did what. Under the bed, the cat found a sock still says the cat was under the bed. Also, do not change every sentence. A paragraph with three different openers and a few simple subject-first sentences reads more naturally than one with an opener in every line.
A quick revision method: underline the first word of every sentence. If three or more in a row match, choose one sentence and ask three questions. When did it happen? Where did it happen? How did it happen? Move the best answer to the front and add the comma.
See the difference
A first attempt
We went to the lake. We set up the tent. We ate lunch. We swam for an hour. We went home.
On Saturday morning, we drove to the lake. Beside the picnic tables, we set up the tent. After lunch, we swam for an hour. Tired and happy, we drove home.
Why this works: The facts are the same, but each sentence now begins in a different way: a time opener, a place opener, another time opener and a how opener. Each opener is followed by a comma, and every sentence still tells who did what. The weak version starts four of five sentences with We, so it sounds like a list.
Worked examples
Example 1 · Move a time detail to the front
Revise: "We played tag after lunch." Start with the time.
- Find the time detail: after lunch.
- Move it to the front: After lunch we played tag.
- Add a comma after the opener: After lunch, we played tag.
After lunch, we played tag.
Example 2 · Name the opener
What kind of opener is each? (a) Behind the shed, I found a ball. (b) Slowly, the door opened. (c) Last winter, we skated every day.
- (a) Behind the shed tells where: a place opener.
- (b) Slowly tells how the door opened: a how opener.
- (c) Last winter tells when: a time opener.
(a) place (b) how (c) time
Example 3 · Fix a flat paragraph
Revise two sentences: "The dog barked. The dog ran across the yard."
- Both sentences begin with The dog. Keep the first one.
- The second sentence can start with a how or place detail. Across the yard is where the dog ran.
- Move it forward and add the comma.
The dog barked. Across the yard, it ran. (Another correct version: The dog barked. Quickly, it ran across the yard.)
Common mistakes
Why this fails: Three or four matching beginnings in a row sound like a list. Move a time, place or how detail to the front of one or two sentences.
Why this fails: The comma tells the reader where the opener ends and the main sentence begins. Write After lunch, we swam.
Why this fails: Only one comma is needed: After lunch, we swam. A second comma, as in After lunch, we, swam, splits the sentence.
Why this fails: Check who did what. Moving only the opener keeps the meaning. Moving a describing word next to the wrong noun can make a sentence silly.
Why this fails: Too many openers make a pattern of their own. Keep a mix: some sentences begin with the subject, some with an opener.

Your turn to write
Write a paragraph of 5–7 sentences about a day you spent outside, such as a day at a park, a rink, a beach or a backyard. Begin with a plain draft where most sentences start with I or We. Then revise it so that at least three sentences start with a time, place or how opener, and no more than two sentences in a row start with the same word.
Helpful sentence starters
- On Saturday morning, …
- Beside the …, we …
- Quietly, …
- After …, I …
- With a …, she …

Answer key
- 1. We baked a cake. We iced the cake. We ate the cake. We shared the cake.
Every sentence in the right answer starts with We, so the beat never changes. The other paragraphs each begin in different ways: time, place or how, plus subject-first sentences. - 2. Place: it tells where
Beside the creek tells where lunch happened. Time would be words like After school. How would be words like Quietly. Reason is not one of the openers in this lesson, and nothing in the sentence says why they ate there. - 3. How: it tells the way
With a grin shows the way Sam opened the box. It does not name a place or a time. The subject is Sam, who comes after the comma, so the opener is not the subject. - 4. After the movie, we walked home.
The comma goes right after the opener, After the movie, and before the main part of the sentence. The other options put the comma inside the opener or after a word in the main part. - 5. At four o'clock, I do my homework.
The time detail at four o'clock moves to the start, with a comma after it, and the rest stays in order. The other options keep the opener at the end, scramble the word order or put the comma in the wrong place. - 6. Early that morning
Early that morning tells when and fits the story. Under the table tells where, but a bus is not under a table. Very red does not tell when, where or how anything happened. Because starts a reason that needs a second part, so Because, the bus pulled away is not a complete thought. - 7. Silently
Silently tells how the cat crept and suits a hunting cat. Yesterday and In the garden give time and place, not how. Loudly is a how opener, but it does not fit a cat creeping up on a bird. - 8. Beside the school gate, our class planted tulips.
Beside the school gate is the place detail. It moves to the front, a comma follows it and the rest keeps its order. The other versions put commas inside the sentence or move the verb to the front. - 9. After the bell, Anna ran to the bus stop.
Only the first one moves After the bell to the front and keeps who did what. The others swap the nouns, so the bell runs or Anna rings it, and the meaning is lost. - 10. I woke up. After breakfast, I got dressed. Then I walked to school.
The best version changes the beginning of two sentences, adds commas and keeps every sentence complete. The version that puts I at the end of each sentence scrambles the word order. The comma-chained version still starts every part with I and is a run-on. The version ending Then, walked to school drops the subject, so that sentence is not complete. - 11. Under the porch the kitten hid.
Under the porch is an opener before the main sentence, so it needs a comma: Under the porch, the kitten hid. In the other sentences the place detail comes at the end, so no comma is needed. - 12. We played hockey in the driveway. Until dark, we kept playing.
The correct revision joins two of the short sentences and starts the next one with a time opener and a comma, so no beginning is repeated. The first option puts the comma inside the opener. The second still begins two sentences with We and repeats played. The third combines two sentences but both remaining sentences begin with We. - 13. The meaning changed: now the squirrel chases the dog.
Swapping the nouns changes who does the chasing. A comma cannot fix that. Revisions should move openers and details, not swap the doer and the receiver. A longer opener would not help. - 14. Change the beginning of two of the four, using a time, place or how opener
Changing two of the four breaks the pattern and still leaves natural subject-first sentences. Changing all six would create a new pattern, adding more The sentences makes the problem worse, and deleting the four would remove facts the paragraph needs. - 15. Sample answer: Strong winds blew. Slowly, the leaves fell. By evening, they covered the yard.
Answers can vary. A good revision starts each sentence differently, puts a comma after each opener, keeps the leaves as the doer in the second and third sentences and does not change the facts.
