• A sentence opener is the first word or phrase in a sentence.

• Different types of openers—such as subject, prepositional, adverbial, clausal, question, and participial phrases—each bring a kind of focus, mood, or detail to a sentence

• They guide the reader's attention and help them understand your writing.

• Sentence openers will make your writing more interesting, natural, and professional.

• They will also reduce repetitiveness in your sentences.

Examples:

• "In Canada, healthcare is publicly funded”

• "Interestingly, many Canadians enjoy outdoor activities year-round.”

• "Although the winters are long, Canadians enjoy outdoor activities”

Types of Sentence openers

Subject opener:

• Why use it: The most straightforward opener, placing the main idea first to clearly introduce the subject of the sentence. It’s direct and easy for readers to follow.

• Example: "Canada has many public universities”

Question opener:

• Why use it: A way to invite the reader’s curiosity or introduce a topic for further exploration. It’s especially effective for engaging readers at the beginning of a paragraph or essay.

• Example: "How does Canada’s healthcare system compare to other countries?”

Prepositional opener (starting a sentence with a prepositional phrase):

What is a Prepositional Phrase?

Preposition: A small word that shows where, when, or how something happens (e.g., in, on, after, with).

Prepositional Phrase = Preposition + Noun/Pronoun (e.g., "in the morning," "under the bed").

Prepositional Opener = Starting with a Prepositional Phrase

The phrase comes first, followed by a comma. It describes the main part of the sentence.

• Examples:
  • "After dinner, we watched a movie." (When?)
  • "On the shelf, the book sat untouched." (Where?)
  • "With a smile, she accepted the award." (How?)

Why Use Them?

Adds variety: Breaks up repetitive "Subject + Verb" starts.

Sets the scene: Quickly tells where/when something happens.

• Without opener:"The cat slept. It was under the table.”

• With opener:"Under the table, the cat slept." (Smoother!)

Clausal opener (starting a sentence with a clause):

What is a Clause?

A clause is a group of words with a subject (who/what) and a verb (action/state).

• Example:"Because she studied hard"(Subject = she, Verb = studied)

Clausal Opener = Starting with a Dependent Clause

A dependent clause cannot stand alone as a full sentence. When used as an opener, it’s followed by a comma and a main clause.

• Example:

• "After the rain stopped, we went outside."

• "If you finish early, you can leave."

Why Use Them?

Makes writing less repetitive than only having the dependent clause after the main clause.

Shows cause/effect, time, or conditions clearly.

• Without opener:"We went outside. The rain had stopped."

• With opener:"After the rain stopped, we went outside." (Smoother!)

Adverb opener (starting a sentence with an adverb):

An adverb modifies a verb, adjective, or another adverb.

Common types:

• How?(slowly, carefully, angrily).

• When?(yesterday, soon, finally).

• Where? (here, outside, everywhere).

• How much? (very, too, almost)

Adverb Opener = Starting with an Adverb

The adverb comes first, followed by a comma if it’s a long or emphatic adverb. Short adverbs often don’t need a comma.

• "Suddenly, the lights went out." (How?)

• "Yesterday, I lost my keys." (When?)

• "Outside, the kids were playing." (Where?)

Why Use Them?

Adds drama or emphasis: "Silently, she tiptoed past the door."

Avoids monotony: Instead of "She tiptoed silently," can be used "Silently, she tiptoed."

Sets tone quickly: "Unfortunately, the concert was canceled."

Participial opener (starting a sentence with a participle):

What is a Participle?

Present Participle: Verb + -ing (e.g., running, laughing).

Past Participle: Often verb + -ed (e.g., excited, broken).

Participial Phrase Opener = Starting with a Participle + Details

The phrase describes the subject of the main clause and is followed by a comma.

• Examples:
  • "Running late,she forgot her keys." (Present participle)
  • "Exhausted from work,he collapsed on the couch." (Past participle)

Why Use Them?

Adds motion or emotion: "Screaming loudly, the child startled everyone."

Can create suspense: "Hidden in the shadows, the figure waited."

Avoids choppiness: Combines two actions smoothly.

Sentence openers and their effects on a sentence

• Let’s use a base sentence with each type of opener and reflect on how each changes the emphasis or meaning

Base sentence: “The students learned valuable skills”

Subject Opener:

• Sentence: "The students learned valuable skills”

• Reflection: Starting with the subject (the students) is direct and straightforward. It emphasizes who is learning without additional context.

Prepositional Opener:

• Sentence: "In the classroom, the students learned valuable skills”

• Reflection: By starting with "In the classroom," the sentence sets a physical context, highlighting where the learning took place and emphasizing the learning environment.

Adverb Opener:

• Sentence: "Interestingly, the students learned valuable skills

• Reflection: Beginning with "Interestingly" adds intrigue or a sense of surprise, suggesting that the fact they learned these skills might be unexpected or noteworthy.

Clausal Opener:

• Sentence: "Although it was challenging, the students learned valuable skills”

• Reflection: Starting with "Although it was challenging" introduces a contrasting or difficult situation, focusing on the effort or obstacles the students overcame to learn these skills.

Question Opener:

• Sentence: "How did the students learn valuable skills?”

• Reflection: By phrasing it as a question, the sentence engages curiosity about the learning process. It shifts the focus to how the learning occurred rather than the learning outcome.

Participial Phrase Opener:

• Sentence: "Working together in groups, the students learned valuable skills”

• Reflection: Beginning with "Working together in groups" emphasizes the method or approach used, suggesting that collaboration was central to the students’ learning experience.
