Etymology and Evolution: The Roots of Confusion
Words evolve. Their origins shape how we use them today, and often, that’s where the confusion begins. Let’s look at where these two words come from and how they’ve morphed over time.
The Origins of “Since”
“Since” dates back to Old English and Middle English. It evolved from the combination of the words “sith” (meaning afterward) and “then.” Later, Latin roots gave it a secondary meaning connected to reasoning—so “since” became not only about time, but also about cause or justification.
The Origins of “Sense”
“Sense,” on the other hand, traces back to the Latin word “sensus,” which means perception, feeling, or meaning. Over time, it evolved to represent not just physical senses like touch or sight, but also mental clarity, judgment, and intuition.
Why the Mix-Up?
Phonetically, “since” and “sense” are almost identical in spoken English, especially in some regional accents. This audio similarity leads to confusion in writing, where spelling rules need to be more precise. Also, both words are abstract, making them trickier to pin down based solely on logic.
Defining “Since”: More Than Just Time
The word “since” is multifunctional. It can serve as a preposition, a conjunction, or an adverb, depending on how it’s used.
1. As a Preposition
Used to express time elapsed from a specific point:

- I left early since I had another appointment.
- She was tired since she hadn’t slept well.
3. As an Adverb

Summary:
- If you’re pointing to time or cause, you’re likely using “since.”
- It’s a temporal and logical connector.
Defining “Sense”: Your Internal Compass
The word “sense” plays several different roles—most commonly as a noun, and occasionally as a verb.
