News Flash: Yesssss! You MAY Split Your Infinitives!

Knowing how I follow developments in the grammar universe, a colleague sent me a recent article from The Economist, a British publication with international coverage and subscribers.

Started in Scotland in 1843, The Economist now claims a reputation for “a distinctive blend of news based on fact, and analysis incorporating The Economist’s perspective.”

The change in The Economist’s style guide that warranted my colleague’s attention relates to the use of infinitives. The editors have declared — at long last — that infinitives may indeed be split.

Infinitive? What’s an infinitive?

If you need a refresher, infinitives are verbs preceded by the preposition to: to leave, to ride, to increase, to get, to explain, to hope, etc.

The problem with infinitives has been the recommendation — some considered it an edict — by esteemed sources that infinitives never be separated (i.e. split) by an adverb.

Were renowned playwright George Bernard Shaw around, he’d no doubt say, “It’s about time!” He once complained to The Economist that one of its editors had insisted on not allowing a split infinitive.

Shaw didn’t like the resulting syntax. He believed that a writer should have a choice on how to express infinitive verb forms.

Let’s look at to leave when the adverb suddenly is included. Shaw most likely would consider the last version the only sensible choice* of these three options. which puts suddenly smack dab in the middle of to and leave.

He decided to leave suddenly.
He decided suddenly to leave.
He decided to suddenly leave.*

Consider the potential interpretation of each statement:

  • He decided to leave suddenly.
    (He gave it some thought and decided to make a quick departure?)
  • He decided suddenly to leave.
    (He made a quick decision to depart, but not necessarily right away?)
  • He decided to suddenly leave.
    (He made a decision to leave immediately.)

Shaw had a point: Not splitting infinitives can rob a statement of clarity. And there are constructions where not splitting infinities sounds odd.

Case Study example

Here’s an example from one of my projects, a case study about a manufacturer of commercial and industrial lighting, where I chose to split the infinitive:

The emergence of LED technology has enabled the manufacturer to dramatically increase fixture life span.

Neither of my other options flows smoothly:

  • The emergence of LED technology has enabled the manufacturer dramatically to increase fixture life span.
  • The emergence of LED technology has enabled the manufacturer to increase dramatically fixture life span.

Here’s another example from the same case study:

Seeking to accurately measure production time, engineers developed a unique approach.

Here’s the sentence without splitting the infinitive:

  • Seeking accurately to measure production time, engineers developed a unique approach.
  • Seeking to measure accurately production time, engineers developed a unique approach.

Again, the alternate versions where the infinitive is not split do not flow well.

To Do or Not To Do

One of the trickiest infinitives involves using a negativeDoes it make more sense to not do something or not to do something?

You should try not to split your infinitives.
You should try to not split your infinitives.

Which sounds better to you? My online research shows that most sources consider either order acceptable.

So there you have it. Infinitives are not joined in a sacred union. They can be separated by an adverb and still capably function.

In addition to the email from my colleague, I heard from a blog follower who wondered what I thought about Infinitives. The Economist added a newsworthy reason to write about it.

Are there other questions lurking out there? Let me know!

    Thank you for your article on splitting infinitives or not. This has been a tickler for me as well. In the two examples you provide, you say that leaving the infinitive intact does not flow well. So, I have a question:what is wrong with these suggestions – the infinitives are intact and to me they sound fine?
    – The emergence of LED technology has enabled the manufacturer to increase fixture life span dramatically. And..
    – Seeking to measure production accurately…
    I agree with you that the examples do not flow easily; I think these do, what do you think?

      Ron, I agree with your revisions. It’s lovely when we have options about how many ways we can rearrange words and still have them make sense and “flow.” That’s one of the challenges of trying to follow what we consider grammar “rules”; they don’t always allow for common sense or judgment by the writer. It’s good to take a step back and allow for all possibilities. Thanks for your insights!
