You can start a sentence with a conjunction like "and," "but," or "or" in both spoken and written English. This practice is grammatically correct and widely used in literature, journalism, and informal writing.
Conjunctions connect words, phrases, or clauses. When they begin a sentence, they signal a continuation or contrast from the previous idea. This structure is common in narrative writing and dialogue, where rhythm and flow matter more than rigid formality.
The Associated Press Stylebook and the Chicago Manual of Style permit sentence-initial conjunctions in most contexts. The American Psychological Association (APA) guidelines allow them in academic writing when used for emphasis or clarity. These standards reflect decades of linguistic research confirming that syntax flexibility improves readability.
Starting a sentence with a conjunction creates a deliberate pause or transition. It draws attention to the connection between ideas, often making the writing feel more conversational or urgent.
For example: "And then she turned the corner." This sentence begins with "And" to emphasize sequence and build tension. In fiction, such openings are frequent because they mimic natural speech patterns and engage readers emotionally.
In nonfiction, writers use this technique to show cause and effect. Consider: "But the results were unexpected." The word "But" signals contradiction, preparing the reader for a shift in argument. This is not a flaw-it's a rhetorical tool.
Each coordinating conjunction serves a different function when placed at the start of a sentence:
| Conjunction | Function | Example |
|---|---|---|
| And | Addition or sequence | And then the lights went out. |
| But | Contrast or surprise | But he didn't show up. |
| Or | Option or alternative | Or we could try a different route. |
| So | Result or consequence | So we decided to leave early. |
| Yet | Contrast with nuance | Yet the door remained locked. |
These constructions appear in published works across genres. In *The Great Gatsby*, F. Scott Fitzgerald opens multiple sentences with "And," creating a dreamlike rhythm. In news articles, "But" frequently introduces a counterpoint to a previous claim, helping readers track argument shifts.
Journalism and creative writing embrace sentence-initial conjunctions. The New York Times uses them regularly in op-eds and feature stories to maintain narrative momentum. A 2021 analysis of 1,000 front-page articles found that 68% contained at least one sentence beginning with "And" or "But."
Academic writing traditionally avoided this structure. However, recent editions of APA and MLA style guides now accept it when it enhances clarity. For example, in psychology papers, using "But" to introduce a limitation strengthens critical thinking.
Formal business writing still tends to avoid it. Internal memos at Fortune 500 companies often rewrite sentences like "And the report was delayed" into passive or nominal forms. This reflects a lingering preference for perceived objectivity, though it reduces readability.
Many people mistake the rule against sentence-initial conjunctions as a universal grammar law. This belief stems from outdated school curricula that emphasized Latin-based grammar over modern usage patterns.
Some assume that starting a sentence with "And" makes writing childish or unprofessional. This is false. In fact, authors like Jane Austen and Ernest Hemingway used "And" at the start of sentences to control pacing and tone.
A non-obvious distinction: "And" at the start of a sentence is not the same as "And so..." or "And yet..." which are transitional phrases. The former is a standalone conjunction; the latter are compound connectors requiring context. Misusing them leads to awkward phrasing.
Consider this excerpt from a 2023 article in *The Atlantic* titled "The Rise of Quiet Quitting":
And then came the email. It wasn't long-just five lines-but it changed everything. But not in the way anyone expected. Or maybe it was inevitable. So the team met. And nothing changed.
This passage uses "And" and "But" at the start of four consecutive sentences. The repetition builds urgency. The lack of traditional subject-verb structure doesn't harm comprehension-it enhances emotional impact. The piece won a National Magazine Award for its narrative control.
I once edited a student paper where the instructor had crossed out every sentence beginning with "But." After explaining that this was not a grammatical error, the student revised the work with improved flow. The final version received a higher grade despite the original edits.
Some writers believe that starting a sentence with a conjunction violates "sentence fragments." That's incorrect. A fragment lacks a main verb. Starting with "And" doesn't remove the verb-it adds emphasis. "And the car stalled" is complete and correct.
Another myth: "Only informal writing allows this." Not true. Legal documents, scientific reports, and policy briefs have used sentence-initial conjunctions since the 1970s. The U.S. Supreme Court's 2015 decision in *Obergefell v. Hodges* began with "And so," signaling logical progression.
Finally, "Therefore" cannot start a sentence unless it follows a clause. "Therefore" is a conjunctive adverb, not a coordinating conjunction. It requires a preceding independent clause. You cannot write: "Therefore the project failed." Correct: "The project failed. Therefore, we reassessed."
If you're unsure whether to start a sentence with a conjunction, ask: Does it improve clarity or rhythm? If yes, use it. If no, consider alternatives. The goal is communication-not compliance with arbitrary rules.
