Sometime vs. Some Time: What’s the Difference?

If you are describing the time at which something happened, or how long it will be before something will happen, it is important to be specific. However, there are times when you do not have enough information to be specific.

Luckily, English has words and phrases perfectly suited to this lack of certainty. Two of them, sometime and some time, are adverbs that many writers get confused. After you read this article, though, you will know which one is which, and what they mean.

What is the Difference Between Sometime and Some Time?

In this article, I will compare some time vs sometime. I will include sentence examples for each word to illustrate its proper meaning and use.

Plus, I will reveal a memory tool you can use to help you decide whether you mean sometime or some time.

When to Use Sometime

For example,

  • “Sometime next month, let’s tear down that old fence and put up a new one,” said Jane.
  • “Sometime between now and whenever you decide to order the pizza, ask Marilyn what she would like on it,” Marvin said.
  • “Sometime last night, a thief broke into the house and stole all of Mother’s fine silver,” said Jimbo.
  • THE headline scrolled through the corner of my computer screen sometime after 10 on Friday night. Fidel Castro had died. It was news I’d been waiting to hear my entire life, and yet I hesitated. –The New York Times

Sometime can also function as an adjective, where it is a synonym of former, and often refers to an “on again, off again” situation, like it does in this sentence:

  • John Frusciante, sometime guitar player for the Red Hot Chili Peppers, is a much more virtuosic player than any of his stand-ins.

Sometime should not be confused with sometimes, an adjective meaning often, but not always.

For example

  • Sometimes, Beth looks like Audrey Hepburn.
