What Does Since Mean?
The word since serves several important functions in English grammar.
Most commonly, it refers to:
- A starting point in time
- A reason or cause
- A connection between past and present events
Because it performs multiple grammatical roles, understanding context becomes important.
Definition of Since
According to major dictionaries, since means:
From a particular time in the past until now.
It can also mean:
Because or considering that.
Since as a Time Expression
This is the most common use.
When you use since, you’re identifying the exact point when something began.
Examples:
- Since Monday
- Since last year
- Since breakfast
- Since graduation
- Since childhood
Notice something interesting. Since always points back to a starting moment.
Why Since Matters in English Grammar
Native speakers use since constantly because it connects past actions to the present.
Consider this sentence:
I’ve lived in Chicago since 2018.
The sentence tells you:
- The action started in 2018.
- The action continues today.
That’s why since often appears with the present perfect tense.
Examples of Since Showing Time
Here are some practical examples:
- We’ve been friends since elementary school.
- She hasn’t called since Friday.
- They’ve operated the business since 2005.
- The museum has attracted visitors since opening day.
- I’ve loved baseball since I was a kid.
Each sentence points to a clear starting moment.
Since as a Reason or Cause
Besides showing time, since can mean because.
In this context, it explains why something happened.
Examples:
- Since it’s raining, we’ll stay indoors.
- Since traffic is heavy, let’s leave earlier.
- Since you’ve already finished, you can relax.
- Since nobody objected, the proposal passed.
When used this way, since introduces a reason.
Since as an Adverb
Sometimes since appears without directly mentioning a specific time.
Examples:
- He moved away two years ago and I haven’t seen him since.
- She left the company in June and hasn’t returned since.
In these sentences, since means “from that time until now.”
Common Phrases with Since
English speakers frequently use these expressions:
Ever Since
Indicates continuous action from a specific moment.
Example:
- I’ve loved reading ever since I learned the alphabet.
Since Then
Refers to everything after a particular event.
Example:
- The restaurant opened in 2010. Since then, it has become a local favorite.
Since When?
Used to express surprise.
Example:
- Since when do you enjoy spicy food?
Long Since
Usually appears in formal writing.
Example:
- The castle has long since disappeared.
What Does Sense Mean?
Unlike since, sense focuses on perception, awareness, understanding, or judgment.
The word appears in everyday conversations, science, psychology, literature, business, and education.
Definition of Sense
The word sense can mean:
- A physical ability to perceive the world
- Awareness of something
- Sound judgment
- Understanding
- Intuition
Because of its flexibility, sense appears in many different contexts.
Sense as Physical Perception
Most people first learn about sense through the five traditional human senses.
These senses help people gather information about the world around them.
The Five Traditional Senses
| Sense | Purpose |
| Sight | Detects light and images |
| Hearing | Detects sound |
| Smell | Detects odors |
| Taste | Detects flavors |
| Touch | Detects pressure, temperature, and texture |
These sensory systems constantly collect information.
For example:
When you smell fresh coffee in the morning, your sense of smell identifies the aroma before you even take a sip.
Sense as Understanding or Judgment
The word sense often refers to intelligence or practical thinking.
This meaning appears in many common expressions.
Examples:
- Common sense
- Sense of responsibility
- Sense of fairness
- Sense of direction
- Sense of purpose
Common Sense
Among all expressions involving sense, common sense is probably the most famous.
Common sense refers to practical judgment based on everyday experience.
Example:
“Common sense is not so common.” — Voltaire
A person who locks their door before leaving home uses common sense.
No instruction manual is necessary.
Sense of Responsibility
This phrase describes awareness of duties and obligations.
Example:
- The manager showed a strong sense of responsibility during the crisis.
Sense of Humor
This refers to the ability to appreciate and understand humor.
Example:
- His sense of humor made stressful meetings easier.
Sense of Direction
Some people naturally know where they are.
Others get lost in a parking lot.
This ability is called a sense of direction.
Sense as a Feeling or Awareness
Sometimes sense refers to an emotional impression rather than a physical perception.
Examples:
- A sense of danger
- A sense of excitement
- A sense of belonging
- A sense of accomplishment
- A sense of confidence
These phrases describe feelings people experience internally.
Example:
After completing a marathon, runners often experience a strong sense of achievement.
Sense as a Verb
Many learners overlook this usage.
As a verb, sense means to detect or become aware of something.
Examples:
- I sense a problem.
- She sensed tension in the room.
- Investors sensed an opportunity.
- The dog sensed danger before anyone else noticed it.
This use often suggests intuition.
