First Priority Usage: Meaning, Correct Usage, Examples, and Common Mistakes

When people want to describe something as extremely important, they often use the phrase “first priority.” You may hear sentences such as “Your health should be your first priority” or “Safety is our first priority.” The meaning is usually clear: something should receive attention before other things. But is “first priority” grammatically correct, and how should you use it naturally in English?

The phrase can be understood easily, but there is an important point about usage. Because priority already refers to something that receives special importance or attention, adding first can sometimes sound repetitive. In many situations, native speakers prefer “top priority,” “highest priority,” or simply “priority.” Still, “first priority” does occur in everyday English, especially when speakers want to emphasize order or importance. This guide explains the meaning, grammar, natural alternatives, and correct examples of first priority usage.

Quick Answer

“First priority” means something considered most important or something that should be dealt with before other matters. It is understandable and commonly used, but “top priority” or “highest priority” is often more natural in polished English. Use “first priority” when emphasizing order or precedence.

Why People Confuse It

The confusion comes from the meaning of the word priority.

A priority is something that deserves attention before less important matters. Because of this, adding first may seem unnecessary.

For example:

• Safety is our first priority. — Common and understandable.
• Safety is our top priority. — More natural and widely preferred.
• Safety is our highest priority. — Strong and formal.

The phrase “first priority” is not automatically wrong. Its acceptability depends on context and what the speaker wants to emphasize.

Another reason for confusion is that English speakers commonly use expressions such as first place, first choice, first concern, and first preference. This can make “first priority” feel completely natural.

First Word: “First”

First is an adjective, adverb, noun, or determiner depending on how it is used.

In “first priority,” it functions as an adjective describing the priority that comes before others.

Examples:

• This is my first concern.
• Health is my first priority.
• She was the first person to arrive.
• Put safety first.

When used with “priority,” first can suggest either greatest importance or the first item in an order of importance.

That distinction matters.

Compare:

Our first priority is fixing the broken equipment.

This can mean fixing the equipment comes before everything else.

Second Word: “Priority”

Priority is a noun meaning something that is more important than other things and therefore deserves attention first.

Examples:

• Customer safety is a priority.
• Education should be a national priority.
• Finishing the project is my top priority.
• The team has several competing priorities.

The word can be singular or plural:

• Priority = one important matter
• Priorities = multiple important matters

Because “priority” already contains the idea of importance and precedence, expressions such as top priority and highest priority are often preferred when you want to identify the most important matter.

When to Use Each

Use “First Priority” When Emphasizing Order

“First priority” works well when you mean something must be addressed before other matters.

Example:

Our first priority is to make sure everyone is safe.

Here, the phrase establishes an order: safety comes before other tasks.

Use “Top Priority” for Natural Everyday English

Top priority is usually the safest choice when you simply mean “the most important thing.”

Getting enough sleep is my top priority this week.

This sounds natural and conversational.

Use “Highest Priority” in Formal Writing

For reports, policies, business communication, and official documents, highest priority can sound more precise.

Protecting customer information remains our highest priority.

Use “Priority” When “First” Is Unnecessary

Sometimes the strongest sentence is the simplest one.

Customer safety is a priority.

There is no need to add “first” if you are not comparing it with anything else.

Here are more than 10 natural examples showing how “first priority” can be used:

Common Mistakes

1. Assuming “First Priority” Is Always Wrong

It isn’t necessarily wrong.

Safety is our first priority.

This is understandable and widely used.

However, top priority may sound more polished when you simply mean “most important.”

2. Using “First Priority” Without Meaningful Emphasis

If there is no sense of order, “top priority” may be better.

Less natural:

Money is my first priority.

More natural:

Money is my top priority.

3. Confusing “Priority” With “Preference”

A priority is something that deserves attention or action first.

A preference is something you like or favor.

For example:

Safety is our priority.

But:

Blue is my preference.

These words are related but not interchangeable.

4. Writing “First Top Priority”

Avoid this combination.

❌ Safety is our first top priority.

Both first and top are trying to express the highest position.

Better:

✅ Safety is our top priority.

5. Overusing “First Priority”

Professional writing usually benefits from variety.

Instead of repeating:

Our first priority is…

you can use:

• Our top priority is…
• Our highest priority is…
• Our main concern is…
• We must first…
• The most important task is…
• Our primary objective is…

Memory Trick

Remember:

Priority = what matters first.

So if you want to emphasize order, think:

First priority = first in line for attention.

If you simply want to say “most important,” remember:

Top priority = most important.

A simple formula is:

Order → first priority
Importance → top priority

This isn’t an absolute grammar rule, but it is a useful guide for choosing the most natural expression.

American vs British English

However, “top priority” and “highest priority” are also widely understood and often sound more natural when describing the single most important matter.

For international English, especially in professional writing, top priority is a particularly safe choice.

Final Verdict

“First priority” is a usable English expression, but it is not always the most natural choice. It works especially well when “first” emphasizes order—something needs to be handled before other matters.

When your intended meaning is simply “the most important thing,” “top priority” is usually the better choice. In formal contexts, “highest priority” can be even more precise.

Remember This

First priority = something that comes first in order or attention.
Top priority = the most important thing.
Highest priority = the matter with the greatest importance.

If you’re unsure, “top priority” is usually the most natural and versatile choice.

Conclusion

Understanding first priority usage is less about memorizing a strict right-or-wrong rule and more about choosing the expression that matches your intended meaning. “First priority” is understandable and commonly used, particularly when you are establishing an order of action. However, because “priority” already suggests importance, “top priority” often sounds smoother when referring to the single most important concern.

For everyday conversation, professional emails, and most general writing, you can confidently use “top priority” when you mean “most important.” If you want to emphasize what should be dealt with first, “first priority” can work well. Choosing between these expressions carefully will make your English sound clearer, more precise, and more natural.
