What Does Each Phrase Mean?

To understand the difference between āa historicā and āan historic,ā you first need to understand how the words a and an work in English.
1. āA historicā
- āAā is used before words that begin with a strong consonant sound.
- āHistoricā begins with a hard āhā soundā: hiss-TOR-ik.
So in everyday English, we say:
ā a historic moment
ā a historic day
ā a historic decision
Examples:
- It was a historic day for our school.
- The team made a historic comeback.
- She gave a historic speech last night.
2. āAn historicā
Long ago, in older British English, many speakers did not pronounce the h in āhistoric.ā
It sounded like: iss-TOR-ik.
Since the word started with a vowel sound (i), they used an instead of a.
ā an historic moment (old/traditional British style)
ā an historic event (formal/historical writing)
Today, most people do pronounce the h, so āan historicā is considered old-fashioned.
Examples:
- The king announced an historic victory.
- It was an historic agreement between two nations.
- They celebrated an historic milestone.
The Key Difference Between āA Historicā and āAn Historicā
Below is the clearest way to tell the two apart:
| Phrase | Pronunciation Rule | Modern Use | Sounds Like | Example Sentence |
|---|---|---|---|---|
| A historic | Used when h is pronounced | ā Modern English ā Schools ā Essays | hiss-TOR-ik | It was a historic match. |
| An historic | Used when h is not pronounced (old style) | ā Traditional British ā Formal speeches | iss-TOR-ik | The treaty was an historic win. |
QUICK TIP TO REMEMBER
š If you say the H strongly, use āa.ā If the H feels silent, use āan.ā
But in todayās English, the H is pronounced, so:
ā āA historicā is the correct and preferred form.

Common Mistakes and How to Avoid Them
Mistake 1: Thinking āan historicā is more correct
ā Incorrect: It was an historic moment.
ā Correct: It was a historic moment.
Why this mistake happens:
Older books and speeches used āan historic,ā so people think it looks more formal or fancy.
How to fix it:
Say the word out loud.
If you can hear the H, choose a.
Mistake 2: Thinking the rule is based on spelling
Some learners think the rule is based on the first letter.
It is actually based on the first sound.
ā Incorrect: We reached an house.
ā Correct: We reached a house.
The H in āhouseā is strong, just like in āhistoric.ā
Mistake 3: Mixing usage within the same text
ā Incorrect: This was a historic step and later became an historic event.
ā Correct: This was a historic step and later became a historic event.
Be consistent throughout your writing.
