Which Sentence Contains a Split Infinitive: A practical guide
A split infinitive occurs when a word or phrase comes between the "to" and the verb form of an infinitive, creating a grammatical construction that has sparked debate among linguists and writers for centuries. Understanding split infinitives is essential for anyone looking to master English grammar and improve their writing skills. This guide will help you identify split infinitives, understand when they should be avoided, and recognize when they are acceptable in modern usage.
What is an Infinitive?
Before we can identify split infinitives, we must first understand what an infinitive is. In English grammar, an infinitive is the base form of a verb, typically preceded by "to." To give you an idea, in the sentence "She wants to eat," "to eat" is the infinitive phrase. The infinitive form of a verb does not indicate tense, person, or number; it simply represents the action in its most basic form Most people skip this — try not to. And it works..
Infinitives can function in various ways within sentences:
- As nouns: "To learn is important."
- As adjectives: "She has a lot of work to do."
- As adverbs: "He came to help.
The infinitive is one of the most versatile grammatical structures in English, and its proper use is fundamental to clear and effective writing.
What is a Split Infinitive?
A split infinitive occurs when a modifier (such as an adverb, adverbial phrase, or prepositional phrase) appears between "to" and the verb in an infinitive phrase. The classic example is the famous Star Trek opening: "To boldly go where no one has gone before." In this case, "boldly" splits the infinitive "to go Worth keeping that in mind..
To identify a split infinitive, look for the pattern: "to + modifier + verb." For instance:
- Correct infinitive: "to quickly run"
- Split infinitive: "to quickly run" (Wait, that's actually not a split infinitive. Let me correct this.
In the split infinitive example, "quickly" comes between "to" and "run," splitting the infinitive.
Identifying Split Infinitives
Identifying split infinitives requires careful attention to sentence structure. Here's how to recognize them:
- Locate the infinitive phrase in the sentence (a verb beginning with "to").
- Check if any words come between "to" and the verb.
- If words do come between "to" and the verb, you have a split infinitive.
Consider these examples:
- "She decided to carefully examine the evidence." (No split infinitive)
- "She decided to carefully examine the evidence." (This is actually the same as above - let me provide a better example)
- "She decided to carefully examine the evidence.And " (This is not split)
- "She decided to examine the evidence carefully. " (Not split)
- "She decided to carefully examine the evidence.
Common Split Infinitive Examples
Split infinitives frequently appear in everyday speech and writing. Here are some common examples:
-
"He wants to really understand the problem." (Split infinitive: "to really understand")
- Correction: "He wants to understand the problem really." (This sounds awkward)
- Better correction: "He really wants to understand the problem."
-
"I need to more carefully consider this decision." (Split infinitive: "to more carefully consider")
- Correction: "I need to consider this decision more carefully."
-
"She promised to always be there for him." (Split infinitive: "to always be")
- Correction: "She promised always to be there for him." (Awkward)
- Better correction: "She always promised to be there for him."
-
"The committee aims to effectively implement the new policy." (Split infinitive: "to effectively implement")
- Correction: "The committee aims to implement the new policy effectively."
-
"They hope to eventually find a solution." (Split infinitive: "to eventually find")
- Correction: "They hope to find a solution eventually."
The Controversy Around Split Infinitives
The debate surrounding split infinitives dates back to the 18th and 19th centuries when grammarians attempted to apply Latin grammatical rules to English. In Latin, infinitives are single words and cannot be split. That said, English infinitives consist of two parts ("to" + verb), making them splittable by nature Not complicated — just consistent..
Despite this linguistic difference, prescriptive grammarians insisted that splitting infinitives was incorrect, and this rule became firmly established in formal writing. In the 20th century, however, linguists and style guides began to relax this rule, recognizing that sometimes splitting an infinitive can improve clarity or avoid awkward constructions.
When to Avoid Split Infinitives
While split infinitives are increasingly accepted in modern English, there are still situations where avoiding them is advisable:
- In formal academic writing: Traditional academic institutions often still prefer avoiding split infinitives.
- When creating awkward constructions: If avoiding the split infinitive makes the sentence sound unnatural or convoluted, it's better to keep the split.
- When following specific style guides: Some style guides, particularly those focused on traditional grammar, may still prohibit split infinitives.
To give you an idea, in the sentence "He attempted to quickly finish the assignment," splitting the infinitive creates a slightly awkward construction. A better alternative would be "He attempted to finish the assignment quickly."
When Split Infinitives Are Acceptable
Modern usage has become more accepting of split infinitives, and they are often preferred in certain situations:
-
For emphasis: Splitting an infinitive can place emphasis on the modifier And that's really what it comes down to..
- "She wants to really understand this issue." (Emphasis on "really")
-
To avoid awkwardness: Sometimes, moving the modifier creates an awkward or unclear sentence Worth keeping that in mind..
- "He decided to more thoroughly investigate the matter." (Better than "He decided more thoroughly to investigate the matter.")
-
In casual and creative writing: Split infinitives are common in fiction, journalism, and other less formal contexts.
Many contemporary style guides, including The Chicago Manual of Style and The Associated Press Stylebook, acknowledge that split infinitives are acceptable when they improve the sentence's flow or clarity.
How to Rewrite Sentences with Split Infinitives
When you identify a split infinitive that you want to revise, consider these options:
-
Move the modifier before the infinitive:
- Original: "She wants to quickly finish her work."
- Revised: "She wants quickly to finish her work." (Often awkward)
- Better: "She quickly wants to finish her work."
-
Move the modifier after the infinitive:
- Original: "He plans to carefully analyze
the data carefully." This revision places the modifier in a more natural position, making the sentence flow better without losing meaning.
-
Rephrase the sentence entirely: Sometimes, a different structure eliminates the need for a split infinitive Small thing, real impact..
- Original: "They asked me to immediately resign."
- Revised: "They asked for my immediate resignation."
-
Use a different verb or phrase: Opt for verbs that don’t require an infinitive or rephrase to avoid the issue.
- Original: "She wants to completely overhaul the system."
- Revised: "She wants to make a complete overhaul of the system."
Balancing Clarity and Tradition
What to remember most? Also, that split infinitives are tools, not rules. But their acceptability depends on context, audience, and intent. Even so, while traditionalists may still bristle at phrases like "to boldly go," modern usage prioritizes clarity and natural expression. Take this: in technical writing or legal documents, precision often trumps stylistic preferences, and a split infinitive might be the most straightforward way to convey meaning.
Worth pausing on this one.
That said, writers should also consider their audience. In academic or formal settings, adhering to conservative guidelines might be necessary. Meanwhile, in creative or conversational contexts, split infinitives can add rhythm and emphasis But it adds up..
Common Pitfalls to Avoid
Even as acceptance grows, some mistakes persist. One frequent error is splitting infinitives unnecessarily, creating awkwardness where none exists. Take this: "They expect to promptly respond" sounds stilted; "They expect to respond promptly" is smoother. Another pitfall is overcorrecting—avoiding split infinitives so aggressively that the sentence becomes confusing or verbose.
Additionally, some writers conflate split infinitives with other issues, such as dangling modifiers or misplaced phrases. Ensuring that the modifier logically connects to the subject is crucial, regardless of its placement.
Conclusion
Split infinitives have evolved from grammatical taboos to accepted nuances in English, reflecting the language’s dynamic nature. While they may still raise eyebrows in certain contexts, their increased prevalence underscores a shift toward valuing clarity and natural expression over rigid prescriptivism. So by understanding when to use them—and when to avoid them—writers can make informed decisions that enhance their message. Now, ultimately, the goal is effective communication, and split infinitives, like any grammatical choice, should serve that purpose. As language continues to adapt, so too should our approach to its rules, embracing flexibility while respecting tradition.
