Frequently Asked Questions about Third Collocations
Is it “a third” or “one-third”?
Both are correct and largely interchangeable. “One-third” is slightly more formal and precise, often used in technical reports or mathematics. “A third” is more common in casual conversation (e.g., “I ate a third of the pizza”).
Do I use “on” or “in” with “third floor”?
In English, we use the preposition “on” for floors of a building. You should say, “I am on the third floor,” not “in the third floor.”
What does “third-party app” mean?
A third-party app is an application created by a developer other than the manufacturer of the device or the operating system. For example, a Facebook app on an iPhone is a third-party app.
Should “third” be capitalized?
Only if it is part of a proper noun (e.g., “The Third Reich”) or at the beginning of a sentence. In general usage, like “the third row,” it remains lowercase.
When do I use “thirds” (plural)?
Use the plural “thirds” when you are referring to more than one part of the three. For example, “He ate two-thirds of the pie.”

Could you briefly explain the difference between 'third' as an ordinal number and 'third' as a noun representing a fraction? I sometimes get tangled up when explaining this to my younger students.
Absolutely, Chloe! When 'third' is an **ordinal number**, it tells you the position in a sequence (e.g., 'She was the *third* person in line'). When 'third' is a **noun representing a fraction**, it refers to one part of three equal parts (e.g., 'I ate *one-third* of the apple'). The key is usually the article: 'the third' for position, 'one-third' for a part. Hope this helps your students!
I appreciate how the article connected grammar and idioms. It's not just about memorizing phrases, but understanding *why* they are used the way they are. 'Third consecutive' is a phrase I'll be using more often in my reports.
