Sometime vs Sometimes: What's the Difference?

Quick Answer

Sometime = at an unspecified point in time
Sometimes = occasionally, now and then
Some time = a period/amount of time

The Three Forms

SOMETIME

At an unspecified time

"Let's meet sometime."

SOMETIMES

Occasionally

"I sometimes forget."

SOME TIME

A period of time

"I need some time."

When to Use Each

SOMETIME - Unspecified Point in Time

Use "sometime" when you don't know exactly when something will happen.

✔Call me sometime this week.
✔I'll finish this sometime tomorrow.
✔We should have coffee sometime.

SOMETIMES - Occasionally

Use "sometimes" to describe how often something happens (not always, not never).

✔I sometimes work from home.
✔Sometimes life is difficult.
✔She sometimes forgets her keys.

SOME TIME - A Period of Time

Use "some time" (two words) when referring to a duration or amount of time.

✔I need some time to think about this.
✔It takes some time to learn a language.
✔We haven't seen each other in some time.

Common Mistakes

✘I sometime eat at that restaurant.→ sometimes
✘Let's meet sometimes next week.→ sometime
✘I need sometime to decide.→ some time

Memory Trick

  • • Sometimes has an "S" at the end = Sometimes happens (frequency)
  • • Sometime = at some point in time (when)
  • • Some time = some amount of time (duration)

Practice

Fill in the blank:

"I _____ make mistakes, but that's how I learn." (sometime / sometimes / some time)
