Quick Answer

Sense is a noun or verb related to meaning, understanding, judgment, or physical perception.

Since is usually a preposition, conjunction, or adverb related to time or reason.

Word	Meaning	Example
Sense	Meaning or understanding	I cannot make sense of this sentence.
Sense	Good judgment	She has good sense.
Sense	Physical ability to perceive	Dogs have a strong sense of smell.
Since	From a past time until now	I have lived here since 2020.
Since	Because	Since it was raining, we stayed home.

A simple rule is:

Sense = meaning, judgment, or perception.
Since = time or reason.

Examples:

This does not make sense.
I have known him since childhood.
Since you are here, we can begin.
She has a good sense of humor.

The Origin of Sense vs Since

The word sense comes from Latin sensus, meaning “feeling,” “perception,” or “meaning.” It entered English through Old French and Middle English. Over time, it developed several related meanings, including physical perception, understanding, judgment, and meaning.

The word since has a different history. It developed from Old English forms related to sith and sithence, meaning “after that” or “from that time.” Its use later expanded to express both time and reason.

The spelling difference exists because these words came from different historical sources. Although they can sound alike or nearly alike in some forms of English, they are not variants of the same word.

British English vs American English Spelling

There is no British-versus-American spelling difference between these words. Both British English and American English use sense and since with the same spelling.

Meaning	British English	American English	Example
Meaning or understanding	sense	sense	That makes sense.
Judgment	sense	sense	Use your common sense.
Physical perception	sense	sense	The sense of smell is strong.
From a past time	since	since	I have worked here since May.
Because	since	since	Since you are ready, we can leave.

The key difference is not regional spelling. It is meaning and grammar.

For example:

British English: I have known her since 2019.
American English: I have known her since 2019.

Both are correct.

Likewise:

British English: That does not make sense.
American English: That does not make sense.

Again, the spelling stays the same.

Which Spelling Should You Use?

Use sense when you mean meaning, understanding, judgment, or perception.

Use since when you mean a period beginning in the past or when you mean “because.”

For US English

American writers should use the same standard spellings:

sense
since

For UK and Commonwealth English

British and Commonwealth writers should also use:

sense
since

There is no need to change either spelling based on location.

For Global English

If you write for an international audience, focus on the meaning rather than regional spelling. Both words are standard worldwide.

A useful test is to replace since with because. If the sentence still works, since may be correct.

Example:

Since I was tired, I went home.

Replace it:

Because I was tired, I went home.

The meaning remains clear, so since is correct.

For sense, try replacing it with “meaning” or “understanding.”

That sentence makes sense.

That sentence has meaning.

Common Mistakes with Sense vs Since

Mistake 1: Using “since” instead of “sense”

Incorrect:

This does not make since.

Correct:

This does not make sense.

The expression is always make sense.

Mistake 2: Using “sense” for time

Mistake 3: Confusing “since” with “because”

Since can mean “because” in some sentences.

Correct:

Here, since means because.

Mistake 4: Confusing “sense” with “meaning”

Sense can mean meaning, but it has other uses too.

Examples:

What is the sense of this sentence?

Mistake 5: Writing “make since”

This is one of the most common spelling errors.
