Basic Meaning
The kanji 二 means "two" and is one of the first numbers learned in Japanese. It is used both as a standalone number and as part of compound words.
Usage in Counting
When counting objects, 二 often appears as ふたつ (futatsu) in native Japanese counting or に (ni) in Sino-Japanese counting. For example, りんごが二つあります means "There are two apples."
Time and Order
二 is commonly used to indicate time (e.g., 二時, 2 o'clock) and order (e.g., 二階, second floor). It is pronounced に (ni) in these contexts.
Common Collocations
- 二つ (ふたつ): two (general counting of objects)
- 二時 (にじ): two o'clock
- 二階 (にかい): second floor
- 二人 (ふたり): two people
Tips
Be careful not to confuse 二 (に) with に as a particle. The context usually makes the meaning clear. Also, remember that counting objects often uses special counters, so 二 alone is rarely used without a counter word.
