Character Breakdown

Meaning and Usage

"一つ" (ひとつ) is a common Japanese counter word used to count one item or thing. It is often used when counting objects in a general, non-specific way. It can mean "one thing," "one piece," or simply "one."

Common Contexts

You will frequently hear "一つ" when ordering food, counting objects, or referring to a single issue or item. It is very versatile and appears in both casual and polite speech.

Collocations and Patterns

  • 一つください: "Please give me one." Used when requesting one item.
  • 一つだけ: "Only one." Used to emphasize a single item or problem.
  • 一つ一つ: "One by one." Used to describe doing something carefully or step-by-step.

Nuances

Using "一つ" implies counting discrete, individual items. It is different from counters that specify types of objects (like 本 for long objects or 枚 for flat objects), but "一つ" is a safe, general-purpose counter.

Common Mistakes

Learners sometimes confuse "一つ" with the number "一" (one) alone. Remember that "一つ" is specifically used as a counter for one item, and it often appears with verbs or requests, while "一" is just the numeral.

Example Sentences

りんごをひとつください。

Please give me one apple.

もんだいはひとつだけです。

There is only one problem.

ひとつひとつていねいにせつめいします。

I will explain each one carefully.
