# What's the difference between "the second" and "a second"?

Here the "second" means 2nd, not 1/60 minutes.

I'd appreciate it if someone gives examples and detailed explanations.

Sorry for lack of context.

Here's an example:

"Ottawa police have apparently discovered a second suspicious package at the Canada Post sorting facility in Ottawa. The Ottawa Citizen’s Meghan Hurley is reporting that package contained a hand."

Why do they use "a second package", not "the second package"?

• Can you give some more context? Like some example usages? I can tell someone something for the second time, I can have a second helping of potatoes, Lady Gaga can win a second Grammy award, a basketball game can resume in the second half, etc. Are you sure this isn't just a question about the difference between "a" and "the"?

This answer is going to assume that your question ultimately expands to be:

How do I tell the difference between the ordinal and the unit of time?

Both the ordinal and the unit of time can be referred to using either article (the definite the or the indefinite a), so that's not going to help.

Commonly, when referring to the ordinal second, you'll see it describing something else:

• The second car has crossed the finished line.
• A second racer has crashed into the wall!
• The competitor must score a second perfect to advance...
• This is now the second time that the racer has earned second place.

Adding to the confusion, the ordinal can refer to "prize" or "place" without adding those additional words and still be valid English:

• Prize
• The second prize goes to Nutley.
• Second goes to Nutley.
• Place
• James lost to King, earning a second place finish.
• James lost to King, earning second.

However, you'll commonly see ordinals with other ordinals:

• I had no idea the car could have leapt from fifth to second!
• That puts Mary in first, Jesse in second, and King in third...
• First, we break into the bank. Second, we loot the bank. Third, we all get arrested...

When second is being used as a unit of time, they'll have a context relating to time:

• I'll be with you in a second.
• I'll fire the second I see it move.
• The second the item goes on sale, I'm buying it.
• A second isn't much time to react.

Just to reiterate, the context is what will tell you one way or the other, and why writing grammatically correct English can be very important. Take the following terse sentence, do you know what they mean?

That's the second second! Wait, do we have a second second too?
