If you are searching for sinse or since, the answer is straightforward: since is the correct standard English spelling, while sinse is a common spelling mistake. These words can be confusing because they sound very similar when spoken, especially in fast or casual speech. However, only since should normally be used in standard English writing.
The word since has several important uses. It can refer to a starting point in time, describe something that has happened continuously from a past moment, or introduce a reason in certain contexts. Sinse, on the other hand, does not have a standard meaning in modern English.
Although they look/sound similar, they serve completely different purposes.
This guide explains sinse or since, including meanings, grammar, examples, pronunciation, history, common mistakes, and easy ways to remember the correct spelling.
What Is “Since”?
Since is the correct and standard English word. It can function mainly as a preposition, conjunction, or adverb, depending on how it is used.
Meaning 1: From a Time in the Past Until Now
One of the most common uses of since is to identify the starting point of an action or situation that continued afterward.
Examples:
“I have lived here since 2020.”
“She has worked there since Monday.”
“We have known each other since childhood.”
In these sentences, since introduces the point when something began.
Meaning 2: From a Particular Past Time
Since can also refer to something that happened after a specific past event.
“I haven’t seen him since the meeting.”
“She hasn’t visited us since last summer.”
The word connects the present situation to a point or period in the past.
Meaning 3: Because
Since can also mean because, particularly when introducing a reason.
For example:
“Since it was raining, we stayed inside.”
Here, since does not refer to time. It means because.
Grammar Rules
Since can be followed by:
- A year: since 2020
- A day: since Monday
- A time: since 8 a.m.
- An event: since the accident
- A clause: since I arrived
It is especially common with perfect tenses:
“I have studied English since 2022.”
“They have lived there since they got married.”
What Is “Sinse”?
Sinse is generally not a standard English word. In most cases, it is simply a misspelling of since.
For example:
❌ “I have lived here sinse 2020.”
✅ “I have lived here since 2020.”
The mistake is understandable because sinse may appear to match the way some speakers pronounce since.
However, in formal, academic, professional, or published writing, you should use since.
Why Do People Write “Sinse”?
English spelling does not always perfectly match pronunciation. The c in since can sound like an s, which may cause learners or writers to spell the word phonetically.
For example:
since → sounds roughly like sins
This can make sinse look plausible, but pronunciation should not be used to determine its spelling.
Is “Sinse” Ever Correct?
For normal modern English writing, sinse should be treated as a spelling error.
You might occasionally encounter it as:
- A typo
- A learner’s spelling mistake
- Informal internet writing
- A deliberately misspelled word in a fictional or humorous context
- A proper name or specialized term
Unless there is a specific reason for the unusual spelling, use since.

When to Use Since vs Sinse
Use “Since” for Time
Use since when something began at a particular time in the past.
Examples:
“I have been studying since morning.”
“She has lived there since 2019.”
“We haven’t spoken since Friday.”
A useful pattern is:
have/has + past participle + since + starting point
For example:
“I have worked here since January.”
Use “Since” for a Reason
You can also use since to mean because.
“Since you’re already here, let’s start.”
“Since it was late, we went home.”
Do Not Use “Sinse”
In standard English, replace sinse with since.
❌ “I haven’t seen him sinse Monday.”
✅ “I haven’t seen him since Monday.”
Since vs For: A Common Grammar Confusion
Another common mistake is confusing since with for.
Use since for a starting point:
“I have lived here since 2020.”
Use for for a duration:
“I have lived here for six years.”
Compare:
- since Monday → starting point
- for three days → duration
- since 2022 → starting point
- for four years → duration
This distinction is especially important when using the present perfect tense.
Easy Memory Trick
Remember:
SINCE = STARTING POINT
FOR = LENGTH OF TIME
So:
“I have studied here since September.”
But:
“I have studied here for two years.”
Pronunciation and Spelling
One reason people search for sinse or since is pronunciation.
The standard spelling is:
since
It is commonly pronounced like “sins.”
The spelling does not use an s where the c appears.
Think of the word as:
S-I-N-C-E
not:
S-I-N-S-E
A good spelling habit is to associate since with other words containing the same -ince pattern, such as once and hence, although their meanings are different.
US vs UK English Notes
There is no meaningful American-versus-British spelling difference here.
Both American English and British English use:
since
The incorrect spelling sinse is not a standard US or UK alternative.
For example:
US English: “I have lived here since 2020.”
UK English: “I have lived here since 2020.”
The spelling remains the same.
Common Mistakes to Avoid
Mistake 1: Writing Sinse
❌ “I have worked here sinse January.”
✅ “I have worked here since January.”
Mistake 2: Confusing Since and For
❌ “I have lived here since five years.”
✅ “I have lived here for five years.”
Mistake 3: Forgetting the Second S Sound
Although since may sound similar to “sins,” its spelling is S-I-N-C-E.
Mistake 4: Assuming Since Always Refers to Time
Since can also mean because.
“Since you are here, let’s begin.”
Understanding the context helps you identify its meaning.
Fun Facts and History
1. Since Has a Long History in English
Since developed from older English forms associated with the idea of “after that” or “from then.” Its meaning gradually expanded into the modern uses connected with time and reason.
2. Since Has More Than One Grammatical Function
Unlike many simple time words, since can work in several ways. It can introduce a starting point, connect a dependent clause, or function as an adverb.
That flexibility is one reason since appears so frequently in English.
Conclusion
When choosing between sinse or since, the correct answer is clear: since is the standard English spelling, while sinse is generally a spelling mistake. Since can be used to identify a starting point in time, such as “since Monday,” and it can also mean “because,” such as “since it was raining.”
The easiest way to remember it is to focus on the spelling S-I-N-C-E. If you’re writing an email, school assignment, article, or professional document, always choose since.
