When it comes to English spelling, few pairs trip people up as often as “since vs sense.” They look almost identical, sound very similar, and both appear in everyday speech.
Yet, one word talks about time or reason, while the other refers to logic or perception. Mixing them up — especially in phrases like “make since” — instantly makes your writing look sloppy.
This guide breaks everything down clearly and deeply. You’ll learn how to tell these words apart, when to use each, and how to never confuse them again. Let’s dive right in.
Quick Summary
If you only remember one thing, remember this:
“Since” is about time or cause. “Sense” is about meaning or perception.
Example:
- âś… It makes sense to leave early.
- ❌ It makes since to leave early.
Here’s a quick comparison to get you started:
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| Since | Conjunction / Preposition / Adverb | Refers to time or reason | We’ve known each other since school. |
| Sense | Noun / Verb | Refers to meaning, understanding, or perception | That doesn’t make sense. |
What Do “Since” and “Sense” Mean?
Before you can master the difference, you need to understand what each word means — and how its function changes depending on its role in a sentence.
Defining “Since”
The word “since” is incredibly flexible. It can act as a conjunction, preposition, or adverb. Each use changes its role slightly but keeps its link to time or cause.
As a Conjunction
When “since” joins two clauses, it often means “because” or “from the time that.”
Examples:
- Since you’re already here, let’s get started. (means because)
- Since I met you, my life has changed. (means from the time that)
Tip: If you can replace “since” with “because” and the sentence still works, it’s a conjunction of reason.
As a Preposition
Used before a point in time, “since” shows when something began.
Examples:
- I’ve lived here since 2015.
- She hasn’t eaten since morning.
This use links the starting point of an action to the present moment.
As an Adverb
When used alone, “since” refers to time already mentioned earlier.
Example:
- I saw her last month, but I haven’t heard from her since.
Here, “since” stands for “since that time.”
Mini Table: Summary of “Since” Uses
| Function | Meaning | Example |
|---|---|---|
| Conjunction | Because / From the time that | Since you called, I replied. |
| Preposition | From a specific time | He’s lived here since 2020. |
| Adverb | After a previous time | We’ve since moved away. |
Defining “Sense”
Now let’s look at “sense.” Unlike “since,” it doesn’t deal with time. It deals with perception, meaning, and understanding.
As a Noun
“Sense” can mean perception, reasoning, or meaning depending on context.
Examples:
- She has a strong sense of smell. (perception)
- That doesn’t make sense. (logic or meaning)
- He has a good sense of humor. (judgment or style)
As a Verb
When used as a verb, “sense” means to detect, perceive, or feel something.
Examples:
- I sensed fear in his tone.
- Animals can sense danger.
Quick Table: Uses of “Sense”
| Function | Meaning | Example |
|---|---|---|
| Noun | Perception, understanding, logic | Use your common sense. |
| Verb | To detect or perceive | She sensed trouble. |
Why Do People Confuse “Since” and “Sense”?
If you’ve ever typed “make since” instead of “make sense,” you’re far from alone. These two words cause confusion for a few real reasons.
Similar Spelling
Both are short, five-letter words beginning with “s” and ending with “nce.” One misplaced vowel easily swaps them.
Close Pronunciation
“Since” /sɪns/ and “Sense” /sɛns/ sound almost identical when spoken quickly, especially in casual speech.
Context-Dependent Meaning
Both appear in everyday conversation, but their meanings rely on sentence context. That’s why many mix them up when writing quickly.
Typing or Hearing Errors
When writing what you hear — especially in texting or social media — “since” often sneaks in for “sense.”
Influence of Common Misuse
You’ll see phrases like “make since” on social media daily. Repetition can trick your brain into thinking it’s right.
Comparing “Since” vs “Sense” — The Core Difference
At their heart, these words serve completely different grammatical and logical roles.

Examples:
- I’ve been studying English since last year. (time)

“Sense”: A Marker of Meaning or Perception
- Shows understanding, awareness, or interpretation.

“Make Since” or “Make Sense”: Which Is Correct?
Here’s the most common confusion: “make since” looks right at first glance — but it’s 100% wrong.
The phrase “make sense” means something is logical, clear, or understandable.
Examples:

Why “make since” is wrong:
“Since” deals with time or reason, not logic. So it can’t pair with make to form a coherent phrase.
