Since or Sense: What’s The Difference?

Since refers to time or a reason, while sense refers to meaning, understanding, or one of your five senses. They sound similar but have completely different meanings and uses.

A few years ago, I was proofreading a student’s essay when I came across this sentence:

“I haven’t seen her sense Monday.”

I smiled because I instantly understood what the student wanted to say. They meant since Monday, but using sense completely changed the sentence. It’s a small mistake that many English learners make because the two words sound almost identical when spoken aloud.

This confusion is more common than you might think. Both words are real English words, so spellcheck often won’t flag the error. That means you need to understand their meanings rather than rely on software to catch the mistake.

If you’ve ever paused while writing and wondered whether to choose since or sense, you’re not alone. By the end of this guide, you’ll know exactly what each word means, where it came from, how to use it correctly, the mistakes to avoid, and an easy memory trick that will help you remember the difference every time.

The Origin of Since or Sense

Even though these words are often mixed up, they come from completely different language families.

Since

The word since comes from the Old English word siththan, meaning after that time or from a particular point in time. As English developed, it also gained the meaning because, allowing it to introduce a reason as well as a time reference.

Sense

This word comes from the Latin sensus, meaning feeling, perception, or understanding. It entered English through Old French and has always been connected with awareness, meaning, judgment, and the five human senses.

Why People Confuse Them

People commonly mix these words because:

• They sound almost identical.
• Both are everyday English words.
• Spellcheck usually accepts both spellings.
• The correct choice depends on the sentence’s meaning, not its pronunciation.
