What Is a Split Infinitive? A Simple Explanation
A split infinitive occurs when an adverb or other word is placed between “to” and the base form of a verb within an infinitive phrase. The traditional rule was to keep “to” directly before the verb, but modern English usage has evolved to accept and often favor flexibility with split infinitives.
Definition List:
- Infinitive: The base form of a verb usually preceded by “to,” such as “to run,” “to eat,” or “to understand.”
- Split Infinitive: When an adverb or word separates “to” from the verb, as in “to quickly finish,” “to boldly go,” or “to really understand.”
Example:
- Not split: “She decided to carefully analyze the data.”
- Split: “She decided to analyze carefully the data.”
Why Do People Care About Split Infinitives?
Historically, strict grammar guides recommended avoiding split infinitives because they were believed to create awkward or ungrammatical sentences. This rule originated from Latin grammar translations, where infinitives are single words that can't be split. However, English permits flexibility, and split infinitives are now considered acceptable, especially when they improve clarity or emphasis.
The Importance of Understanding:
- Clarity: Sometimes splitting an infinitive makes the meaning clearer.
- Emphasis: It can highlight an important word or idea.
- Style: Many modern writers prefer natural, flowing sentences over rigid rules.
When Are Split Infinitives Useful?
Split infinitives can be a stylistic choice to enhance readability or emphasize particular parts of a sentence. For example:
- “To boldly go where no man has gone before” (famous Star Trek phrase)—the split infinitive emphasizes “boldly.”
- “She decided to quickly finish her project”—the placement of “quickly” makes the urgency clearer.
Avoiding split infinitives isn't always better; sometimes, forcing the infinitive to stay intact can produce less natural sentences. The key is knowing when and how to use or avoid them.
How to Identify and Correct Split Infinitives
Identifying split infinitives is straightforward: look for “to” followed by an adverb or another word and then a verb. Correcting them involves rewriting the sentence to keep “to” and the verb together or restructure for flow.
Common Steps:
- Find the infinitive: look for “to” + verb.
- Determine if anything interrupts the “to” and verb.
- Decide if the split affects clarity or style.
- Rewrite if necessary, either by moving words or restructuring.
Example:
- Original: “He decided to quickly finish the report.”
- Corrected: “He decided to finish the report quickly.”
- Or: “He decided to rapidly finish the report.”
Tips for Using Split Infinitives Effectively
- Use sparingly: Overuse can make your writing seem cluttered.
- Prioritize clarity: If splitting an infinitive makes your sentence clearer or more natural, go ahead.
- Match tone and style: Formal writing may favor avoiding splits; conversational, creative writing may embrace them.
- Read aloud: If the split sounds awkward, revise for fluency.
Common Mistakes and How to Avoid Them
| Mistake | Why It’s a Problem | How to Fix It |
|---|---|---|
| Splitting for the sake of it | Creates awkward sentences | Only split if it improves clarity or emphasis |
| Overcorrecting and avoiding all splits | Leads to stilted writing | Use split infinitives when natural and beneficial |
| Moving words unnecessarily | Alters meaning or flow | Keep revisions simple and logical |
Variations and Flexibility in Usage
Split infinitives often serve as stylistic tools, not grammatical errors. Useful variations include:
- Rearranging words for emphasis:
- “She decided to quickly and efficiently complete her task.”
- Using alternative sentence structures:
- “She decided to complete her task quickly and efficiently.”
- Combining multiple adverbs:
- “He wanted to boldly and confidently speak his mind.”
Proper Order in Multiple Words with Infinitives
When multiple adverbs or modifiers are involved, proper order can impact sentence clarity:
- Correct: “He decided to carefully, thoroughly, and quickly analyze the data.”
- Alternative: “He decided to analyze the data carefully, thoroughly, and quickly.”
Ensure that the modifiers are in a logical order, often following the conventions of natural speech and style.
