Since and sense are easy to mix up because their spellings look similar. However, they have different meanings and uses. Since refers to a starting point in time or a reason, while sense relates to understanding, perception, or judgment. Knowing the difference helps you choose the right word.
Quick Answer:
- Since: Shows when something began or explains why something happened.
- Sense: Describes physical perception, understanding, feelings, or judgment.
What Does Since Mean?
Since can be a preposition, conjunction, or adverb. It refers to a point in the past or introduces a reason.
Examples:
- I’ve lived here since 2021. (preposition)
- Since it was late, we decided to leave. (conjunction)
- We met years ago and haven’t spoken since. (adverb)
Use since with a starting point, such as Monday or 2021. It often appears with the present perfect when something began in the past and continues now. It can also mean because when it introduces a reason.
What Does Sense Mean?
Sense is a noun or verb connected with the five senses, awareness, understanding, and judgment.
As a noun, it can describe physical perception or the ability to understand something:
- She has a strong sense of smell.
- Your explanation makes sense.
- He has a good sense of humor.
Common expressions include common sense, meaning practical judgment, and make sense, meaning to be clear or logical. As a verb, sense means to notice or become aware of something: “I sensed that something was wrong.”
