Welcome! If you’ve ever wondered about split infinitives and whether they’re grammatically correct, you’ve come to the right place. I’m here to provide you with the most accurate and comprehensive explanation, so you can confidently understand and use split infinitives in your writing.
Split infinitives often spark debate among writers and grammarians. The question is: what exactly are split infinitives, and should you avoid them or use them freely? The clear answer is that a split infinitive occurs when an adverb or other word interrupts the “to” and the base form of a verb. For example, “to quickly run” splits the infinitive “to run” with the adverb “quickly.”
But why do some people insist on avoiding split infinitives, while others see them as perfectly acceptable? Keep reading, and I’ll guide you through the nuances, rules, tips, and common mistakes related to split infinitives. Whether you’re a student, professional, or casual writer, mastering this aspect of grammar will enhance your clarity and style.
Understanding Split Infinitives
Definition:
A split infinitive occurs when a word (usually an adverb) separates “to” from a verb in its infinitive form, as in “to boldly go.”
Historical Context:
Split infinitives date back to Latin, which lacks infinitives and doesn’t allow such constructions. English adopted the form from Latin-influenced grammar rules but has since developed more flexible usage, leading to ongoing debates about their correctness.
Why They Matter:
Proper use of split infinitives can improve sentence clarity, emphasis, and flow. Misuse or overuse, however, can clutter or weaken your writing.
The Anatomy of a Split Infinitive
| Element | Description | Example |
|---|---|---|
| Infinitive | The base form of the verb preceded by "to" | to see, to run, to decide |
| Splitting Word | An adverb, adjective, or phrase inserted between "to" and the verb | to carefully explain, to boldly go, to quickly finish |
Common Features of Split Infinitives:
- They usually involve an adverb (e.g., "quickly," "clearly," "completely")
- They are often used to emphasize or modify the verb
- They can sometimes be awkward or redundant if not used carefully
Why Are Split Infinitives Sometimes Controversial?
Historical Grammar Rules:
For centuries, traditional grammar rules aimed to emulate Latin structures, discouraging split infinitives. Writers believed that keeping “to” and the verb together was more elegant and correct.
Modern Usage:
Contemporary English grammar recognizes that splitting infinitives can sometimes improve clarity and emphasis. Many style guides now accept split infinitives, especially when avoiding them results in awkward or convoluted sentences.
Professional Recommendations:
- The Chicago Manual of Style states that split infinitives are “permissible and often preferable.”
- The Associated Press Stylebook allows split infinitives for clarity.
- Strunk and White’s The Elements of Style advise against splitting infinitives when it hampers readability but accept their use when necessary.
When Should You Use or Avoid Split Infinitives?
Use them when:
- They improve clarity or emphasis
- Avoiding split infinitives results in awkward sentences
- The adverb or phrase provides important emphasis or meaning
Avoid them when:
- They make sentences cluttered or confusing
- Your audience prefers traditional or formal writing styles
- You are following strict conservative style guides (though many now accept split infinitives)
Tips for Success with Split Infinitives
- Prioritize clarity: If inserting an adverb makes your sentence clearer, go ahead.
- Be mindful of tone: Formal writing may favor avoiding split infinitives; casual writing allows more flexibility.
- Practice rewriting: If a split infinitive sounds awkward, try rephrasing without splitting.
- Use with purpose: Don’t split just to be trendy; do it to enhance readability.
- Balance style and clarity: Sometimes a split infinitive is more natural and conversational.
Common Mistakes & How to Avoid Them
| Mistake | Why It Happens | How to Avoid |
|---|---|---|
| Overusing split infinitives | Trying too hard to emphasize | Use sparingly; only when it improves clarity or emphasis |
| Splitting unnecessarily long phrases | Reduces readability | Keep phrases concise and consider rephrasing |
| Splitting when it creates ambiguity | Confuses the reader | Read sentence aloud; if confusing, reword |
Example of a mistake:
Incorrect: “She decided to really quickly finish her homework.”
Corrected: “She decided to finish her homework really quickly.”
Variations and Related Constructions
While split infinitives are straightforward, similar structures can cause confusion:
- Multiple particles: “to boldly and quickly go” (which is acceptable)
- Multiple split points: Generally avoided unless necessary for clarity
- Using other adverbs or phrases: Can sometimes cause awkwardness, so choose carefully
Why Rich Vocabulary Truly Matters in Grammar
Expanding your vocabulary helps you choose the right words and idiomatic expressions, making your writing more precise and engaging. It also helps you understand subtle grammatical nuances, such as when split infinitives are justified or preferred.

When you have multiple infinitives or complex sentences, follow these guidelines:
