Somedays or some days is a common spelling question that can confuse English learners and even experienced writers. Both forms may look natural, but only one is correct in standard English. Understanding the difference can help you write clearer sentences, avoid spelling mistakes, and express your thoughts accurately.
The correct spelling is some days, written as two separate words. It refers to certain days, an unspecified number of days, or occasional periods of time. The single-word form, somedays, is generally considered incorrect in standard English.
Many people also confuse some days with someday, which is a correct word with a different meaning.
In this guide, you’ll learn the correct spelling, meaning, grammar rules, pronunciation, common mistakes, and practical examples. You’ll also discover how to choose between some days, someday, and sometimes.
Somedays or Some Days: Quick Answer
Some days is correct, while somedays is incorrect in standard English.
The phrase some days consists of two separate words:
- Some: A determiner indicating an unspecified quantity.
- Days: The plural form of the noun day.
Together, these words describe an unspecified number of days or particular days within a period.
Quick Comparison Table
| Word or Phrase | Correct? | Meaning | Example |
|---|---|---|---|
| Some days | Yes | Certain days or an unspecified number of days | Some days are harder than others. |
| Somedays | No | Nonstandard spelling of some days | Somedays I feel tired. |
| Someday | Yes | At an unspecified time in the future | Someday, I will travel abroad. |
| Sometimes | Yes | Occasionally | Sometimes I wake up early. |
Easy rule: Use some days when discussing multiple days. Use someday when referring to an unspecified future time.
What Does Some Days Mean?
The phrase some days refers to certain days or an unspecified number of days. It can describe experiences, feelings, activities, or situations that occur on particular days.
It does not identify exactly which days are being discussed.
For example:
- Some days I feel happy and energetic.
- Some days are better than others.
- I work from home some days.
- Some days, the weather changes quickly.
- She feels tired on some days.
In these sentences, some days describes particular days without naming them.
Some Days as an Unspecified Number of Days
The phrase can also refer to a number of days without specifying exactly how many.
Examples:
- We spent some days exploring the countryside.
- The project may require some days of preparation.
- I need some days to think about the decision.
- He stayed with his relatives for some days.
In everyday English, phrases such as a few days or several days may sound more natural when describing a duration.
For example:
Natural: I need a few days to finish my work.
Also possible: I need some days to finish my work.
Both are understandable, but the first is more common in ordinary conversation.
Some Days When Describing Occasional Experiences
You can also use some days to describe feelings or situations that change from day to day.
Examples include:
- Some days I enjoy being alone.
- Some days I prefer coffee instead of tea.
- Some days I feel more confident.
- Some days everything seems difficult.
- Some days I wake up before sunrise.
These examples show that the situation occurs on certain days rather than every day.
Is Somedays a Word?
Somedays is not a standard English word. It is usually a misspelling of some days.
People sometimes combine the two words because they sound like a single expression when spoken.
However, standard English spelling requires a space between some and days.
Incorrect or Correct Examples
Incorrect: Somedays I feel tired after work.
Correct: Some days I feel tired after work.
Incorrect: Somedays are more stressful than others.
Correct: Some days are more stressful than others.
Incorrect: I exercise somedays.
Correct: I exercise some days.
Incorrect: Somedays I want to stay home.
Correct: Some days I want to stay home.
Although somedays occasionally appears in informal online writing, creative titles, or social media captions, it is not the accepted spelling for ordinary sentences.
For school assignments, professional emails, academic writing, and published articles, always use some days.
Somedays or Some Days: Understanding the Grammar Rule
The difference becomes easier to understand when you examine the grammatical structure.
Some days is a phrase made from a determiner and a plural noun.
Some Is a Determiner
The word some indicates an unspecified amount or number.
Examples:
- Some people enjoy reading.
- Some students prefer online classes.
- Some books are expensive.
- Some days are difficult.
In each example, some describes an unspecified quantity.
Days Is a Plural Noun
The word days is the plural form of day.
Examples:
- One day
- Two days
- Several days
- Some days
- Many days
Because some and days are separate grammatical elements, they remain separate words.
Can Some Days Function as an Adverbial Phrase?
Yes. Some days can function as an adverbial phrase of time when it explains when something happens.
Consider this sentence:
Some days, I walk to school.
Here, some days tells us when the action occurs.
It answers the question:
When do I walk to school?
Answer: On some days.
This is why the phrase often appears at the beginning or end of a sentence.
Some Days or Someday: What’s the Difference?
One major reason people confuse some days with somedays is the existence of the correct word someday.
Although some days and someday look similar, they express different ideas.
Meaning of Some Days
Some days refers to certain days or an unspecified number of days.
Examples:
- Some days I study for three hours.
- Some days are more productive than others.
- I visit my grandparents some days.
The phrase refers to multiple days.
Meaning of Someday
Someday means at an unspecified time in the future.
It is written as one word.
Examples:
- Someday, I want to become a doctor.
- I hope to visit Japan someday.
- Someday, my dreams will come true.
- She wants to start her own business someday.
The word expresses a future possibility, plan, or hope.
Some Days or Someday Comparison
| Feature | Some Days | Someday |
|---|---|---|
| Spelling | Two words | One word |
| Grammar | Determiner + plural noun | Adverb |
| Meaning | Certain days | An unspecified future time |
| Time reference | Past, present, or future | Usually future |
| Example | Some days I feel tired. | Someday I will succeed. |
Memory trick: If you mean certain days, write some days. If you mean an unknown future time, write someday.
Some Days or Sometimes: Are They Interchangeable?
The expressions some days and sometimes have similar meanings, but they are not always interchangeable.
Some days specifically refers to days on which something happens.
Sometimes means occasionally or at certain times.
Examples of Some Days
- Some days I work late.
- Some days I feel nervous.
- Some days I skip breakfast.
- Some days I enjoy walking in the rain.
Examples of Sometimes
- Sometimes I work late.
- Sometimes I feel nervous.
- Sometimes I skip breakfast.
- Sometimes I enjoy walking in the rain.
Both expressions work in these examples.
However, sometimes can refer to events happening at any time, not necessarily on different days.
For example:
Sometimes I drink tea twice a day.
This sentence describes occasional behavior.
Replacing sometimes with some days changes the focus to particular days.
When Should You Use Each Expression?
Use some days when your main focus is on particular days.
Use sometimes when your focus is on how frequently an action or experience occurs.

Common Mistakes With Somedays or Some Days
Several mistakes occur because people confuse spelling, meaning, or sentence structure.
Mistake 1: Writing Somedays as One Word
Incorrect: Somedays I feel exhausted.
Correct: Some days I feel exhausted.
Remember that some days always contains a space in standard English.
Mistake 2: Using Someday for Multiple Days
Incorrect: Someday I work from home, but on other days I go to the office.
Correct: Some days I work from home, but on other days I go to the office.
Here, the sentence discusses a recurring schedule, not an unspecified future event.
Mistake 3: Using Some Days for a Future Dream
Incorrect: Some days I will become a successful writer.
Correct: Someday I will become a successful writer.
The correct word is someday because the sentence expresses a future goal.
Mistake 4: Confusing Some Days With Every Day
Some days means certain days.
Every day means each day without exception.
Compare:
- Some days I exercise.
- Every day I exercise.
The first sentence describes an activity that happens on certain days.
The second indicates a daily routine.
Mistake 5: Confusing Some Days With A Few Days
These expressions can overlap, but they are not always interchangeable.
Some days: I feel tired some days.
A few days: I will return in a few days.
The first refers to particular days when something happens. The second describes a short period of time.
Why Do People Confuse Somedays or Some Days?
There are several reasons for this common spelling mistake.
Similar Pronunciation
Some days and somedays would sound identical when spoken.
Because English speakers do not pronounce spaces, listeners cannot determine the spelling from pronunciation alone.
Confusion With Someday
The correct single-word spelling someday can lead people to assume that somedays is also acceptable.
However, adding an s changes the grammatical structure.
Someday is an adverb.
Some days is a phrase containing a determiner and a plural noun.
Informal Online Writing
Social media posts, text messages, and informal comments sometimes contain somedays.
Repeated exposure to this spelling can make it appear correct.
However, frequent online usage does not automatically make a spelling standard.
Autocorrect or Typing Errors
People may accidentally remove the space while typing quickly.
Proofreading helps identify these errors before submitting or publishing written content.
