Which Sentence Must Be Revised To Eliminate A Split Infinitive? | Clear Grammar Fix

Questions that quote a prompt about revising a sentence to eliminate a split infinitive can look scary at first glance. In reality, they test one narrow point of grammar: whether a word has been pushed between to and a base verb.

This article explains split infinitives, shows typical exam patterns, and gives you a simple method for answering these questions. Once you know the pattern, these items stop feeling like trick questions on grammar tests.

What A Split Infinitive Is In English Grammar

In English, an infinitive usually appears as the word to plus a base verb such as go, read, or write. When another word slides between these two parts, you have a split infinitive. Classic textbook examples include phrases like to quickly finish or to fully understand.

The Merriam-Webster definition describes a split infinitive as an infinitive with a word placed between to and the verb. Language references such as the Cambridge Dictionary entry point out that some writers still avoid this pattern in formal contexts, which is why it appears so often in school questions.

Typical Split Infinitive Patterns

Most split infinitives in assignments and exams follow a small set of patterns:

• To + adverb + verb: to quickly finish, to carefully check.
• To + degree word + adverb + verb: to more fully explain.
• To + short phrase + verb: to in no way change.

Each pattern places extra material between the marker to and the base verb.

Examples Of Split Infinitives And Revisions

The table below shows how a sentence with a split infinitive can be rewritten so that no word stands between to and its verb.

Original Sentence	Revised Without Split Infinitive	Notes
She decided to quickly finish her homework.	She decided to finish her homework quickly.	Move the adverb after the verb phrase.
The coach told them to fully try this time.	The coach told them to give a full effort this time.	Replace the split with a short phrase.
He wanted to completely change the topic.	He wanted to change the topic completely.	Place the adverb after the object.
They promised to carefully follow the rules.	They promised to follow the rules carefully.	Keep the verb and its object together.
The speaker tried to fully connect with the audience.	The speaker tried to connect fully with the audience.	Shift the adverb to the right of the verb.
We hope to better understand the data.	We hope to understand the data better.	Move the degree word to the end of the clause.
The plan is to completely and permanently solve the issue.	The plan is to solve the issue completely and permanently.	Keep both modifiers after the full verb phrase.

On worksheets the sentences are often shorter than these examples, yet the same structure appears: a word or phrase separates to from its verb.

Exam Version Of Which Sentence Must Be Revised To Eliminate A Split Infinitive?

When an exam uses that exact wording, you usually see a list of four sentences. Only one includes a split infinitive, and you must spot it and think of a smooth revision.

In this setting, your job is to follow the rule on the page: find the option where a word sits between to and a base verb, then form a version in your mind with that word in a better spot.

Step 1: Scan For Infinitives

Take a quick pass through the answer choices and underline each to that comes right before a base verb, not cases such as “go to the library.”

Step 2: Check What Sits After To

Next, check the word right after each marked to. A verb means no split; an adverb or short phrase between to and the verb marks a split infinitive.

Step 3: Try A Simple Revision

Once you see a split infinitive, test a change in your head by moving the adverb before or after the infinitive phrase. If the new version keeps the meaning and reads smoothly, it works.

Which Sentence Should Be Revised To Remove A Split Infinitive In Grammar Tasks

Textbooks and online quizzes sometimes use slightly different wording. Instead of asking which sentence must be revised to eliminate a split infinitive?, a worksheet might say “Which sentence contains a split infinitive?” or “Select the sentence with a split infinitive.” The surface text shifts, but the skill stays the same.

Every version of this prompt sends you hunting for the same pattern: to followed by an adverb or short phrase, and then a base verb. Once you train your eyes to catch that structure, this family of questions becomes far less stressful.

Common Alternate Prompts

• “Choose the sentence that uses a split infinitive.”
• “Select the sentence that should be revised to fix a split infinitive.”
• “Rewrite the sentence to remove the split infinitive.”
• “Find and correct the split infinitive in the sentence below.”

Whenever you meet one of these prompts, remind yourself that the target is the same: a word between to and a base verb that can be moved elsewhere.

When Writers Sometimes Keep A Split Infinitive

School questions usually ask you to remove split infinitives, yet many modern style guides accept them in everyday writing. Articles on sites such as ThoughtCo note that writers often keep a split infinitive when moving the adverb would harm the rhythm or create confusion.

Take this pair of sentences:

We expect our results to more than double next year.
We expect our results more than to double next year.

The first sentence contains a split infinitive and reads smoothly. The second avoids the split yet feels stiff and slightly unclear. In real-world writing, many editors prefer the first version. In exam settings, though, you should follow the directions printed on the page, which often ask you to remove the split even when both versions sound fine.

Step-By-Step Strategy For Split Infinitive Questions

To bring all of this together, use the short routine below whenever you face a question that asks which sentence must be revised to eliminate a split infinitive? or a close variation of that wording.

1. Read every option once. Take in the meaning of each sentence before you start marking anything.
2. Underline every infinitive. Mark each instance of to followed by a base verb.
3. Circle words between to and the verb. Any adverb or short phrase in that spot marks a possible split infinitive.
4. Test a revision in your head. Move the adverb before or after the infinitive phrase and mentally listen to the new sentence.
5. Compare options. Choose the sentence where this change removes the split and the remaining options do not contain that pattern.

After you run through this routine a few times, you start to spot split infinitives almost automatically, even when the sentences are long or technical.

Quick Checklist For Split Infinitive Exams

When a worksheet or exam asks a question about split infinitives, keep this short checklist in mind while you work through the answer choices:

• Scan each sentence for to followed by a base verb.
• Watch for adverbs or short phrases that stand between to and the verb.
• Move the extra word to the left or right in your head and test whether the sentence still makes sense.
• Pick the sentence where that simple change removes the split infinitive and the other sentences do not show that pattern.

With practice, this checklist turns split infinitive questions from a surprise into a routine task in many standard grammar tests.
