What Is A Split Infinitive?

A split infinitive happens when a word, often an adverb, is placed between “to” and the base form of a verb. For example, in the phrase “to boldly go,” the word “boldly” separates “to” and “go,” making it a split infinitive. Split infinitives are a topic of debate in grammar. Some argue they should be avoided because they were traditionally seen as incorrect, while others accept them as natural in modern English. Here’s why they occur: they can emphasize meaning or improve sentence flow. For example, “She decided to quickly leave” might sound smoother than “She decided quickly to leave.” Ultimately, it’s a style choice. While avoiding split infinitives can create a more formal tone, using them can make writing clearer and more natural.

Examples of Split Infinitives:

1. To boldly go where no one has gone before. (“Boldly” splits “to” and “go.”)
2. She promised to completely understand the problem before responding. (“Completely” splits “to” and “understand.”)
3. He decided to carefully consider his options. (“Carefully” splits “to” and “consider.”)
4. They tried to not argue during the meeting. (“Not” splits “to” and “argue.”)
5. The teacher asked us to thoroughly review the material. (“Thoroughly” splits “to” and “review.”)

FAQs About Split Infinitives:

1. Why are split infinitives controversial?

• Traditional grammar rules (influenced by Latin) considered infinitives inseparable, so split infinitives were seen as incorrect. However, modern English usage often prioritizes clarity and natural flow, making split infinitives acceptable in most cases.

2. Should I avoid split infinitives?

• It depends on your audience and purpose. For formal writing, you might avoid them to maintain a polished tone. In casual or conversational writing, they are perfectly fine if they improve clarity.

3. What are the benefits of split infinitives?

• They can make sentences easier to read and emphasize meaning. For example, “to really try” sounds more natural than “really to try.”

4. How can I rewrite sentences to avoid split infinitives?

• Place the modifier before or after the entire infinitive phrase:
  • Split: She wants to quickly finish her homework.
  • Revised: She wants to finish her homework quickly.

5. Are split infinitives grammatically incorrect?

• No. While some traditionalists frown on them, modern grammar experts agree they are acceptable when they improve sentence clarity or flow.
