Writers often confuse sometimes (one word) and some time (two words). One is an adverb of frequency; the other is a noun phrase meaning a period of time.
Below are clear rules, quick tests, many wrong/right pairs, and rewrites you can copy for work, school, and everyday contexts.
Quick answer
Use sometimes (one word) for "occasionally." Use some time (two words) for "a period of time." Use sometime (one word) for "at an unspecified time."
- sometimes = occasionally (adverb of frequency)
- some time = a span or amount of time (noun phrase)
- sometime = at an unspecified time
- Substitution test: if "occasionally" fits → sometimes; if "a while" fits → some time
Core explanation: frequency vs duration
Sometimes modifies how often something happens: it moves with or near the verb. Examples: "I sometimes go," "She is sometimes late."
Some time names an amount of time and behaves like an object: "I need some time," "He spent some time." Sometime (one word) means an unspecified moment: "Let's meet sometime next month."
- Adverb position → sometimes. Object/amount → some time.
- Wrong: "I need sometimes to finish this."
Right: "I need some time to finish this." - Wrong: "Sometimes a meeting lasts an hour."
Right: "Sometimes meetings last an hour."
How to fix your sentence - a 3-step test
Apply these substitutions to the whole sentence, not just the phrase.
- Try "occasionally." If it reads naturally, use sometimes.
- Try "a while" or "a period of time." If that fits, use some time.
- If you mean "at an unspecified time," use sometime (one word).
- Rewrite:
Original: "She wants sometimes to talk." Test: "occasionally" → awkward. "a while" → "She wants a while to talk." Better: "She wants some time to talk." - Rewrite:
Original: "Can you sometimes help me?" If you mean "occasionally," keep it. If you mean "at an unspecified time," write: "Can you help me sometime?" - Rewrite:
Original: "I sometimes two hours on weekends." Fix: "I spend some time - about two hours - on weekends."

Short, copyable examples with the wrong form and a clean correction.
- Work - Wrong: "Can we sometimes schedule a longer review?"

Right: "Give me some time to call you back." - Casual - Wrong: "Can we meet sometimes this week?"

Try your own sentence
Test the full sentence with the three-step substitution. Context usually shows the right answer faster than checking the phrase alone.
Real usage and tone - how meaning shifts
Sometimes frames behavior as a recurring pattern and reads softer: "He sometimes misses deadlines" implies an occasional habit. Some time is concrete and often prompts scheduling or action: "I need some time" suggests you want the listener to allow space.
- Formal writing: prefer precise alternatives like "occasionally" or "for a period of time."
- Emails: "I need some time" usually asks for scheduling; "I sometimes" simply describes a habit.
Spacing, hyphenation, and nearby lookalikes
Use these quick rules to avoid visual mistakes: sometimes = one word; some time = two words; sometime = one word. None take a hyphen.
Related pair: a while (two words, noun phrase) vs awhile (one word, adverb). Example: "I'll wait for a while" vs "Stay awhile."
- Don't write "some-time."
- Use "sometime" for an unspecified single time; use "sometimes" for frequency; use "some time" for duration.
Memory trick - remember quickly
Think: sometimes = some-times (how often). Some time = some + time (an amount). Use the substitution test: "occasionally" → sometimes; "a while" → some time; if you mean "unspecified" → sometime.
- If the phrase is the object of verbs like need/spend/take, choose some time.
- If the word moves around the verb and shows frequency, choose sometimes.
Similar mistakes to watch for
Watch these common confusions and prefer clearer phrasing when a sentence feels ambiguous.
- Wrong: "for sometime" →
Right: "for some time" or better: "for a while." - Wrong: "I'll wait for sometime." →
Right: "I'll wait for some time" or "I'll wait for a while." - Don't use "awhile" unless you need the adverb form; otherwise use "a while."
FAQ
When should I use 'sometime' instead of 'sometimes'?
Use sometime for "at an unspecified time" (Let's meet sometime). Use sometimes for "occasionally" (I sometimes go).
Is 'some time' always two words?
Yes. When you mean an amount or period, write some time: "I need some time to think."
Can I replace 'some time' with 'a while'?
Often. Both indicate duration. "I need some time" → "I need a while" (the latter is more casual).
How do I check quickly in a sentence?
Try "occasionally" (fits → sometimes). Try "a while" or "a period of time" (fits → some time). If you mean "unspecified time," use sometime.
Will a grammar checker catch this?
Many do, but practicing the substitution test and using these examples will help you fix errors without relying on tools.
Want a quick check for your sentence?
Run the three-step substitution test and paste the full sentence into a grammar tool for a second opinion. That combination fixes most errors fast and helps you remember the pattern.
