Meaning and Usage
"唯一" (ゆいいつ) means "only," "sole," or "unique." It is used to emphasize that something is the one and only of its kind or the single instance in a particular context.
Common Contexts
You will often see "唯一" used to highlight exclusivity, such as the only friend someone has, the only problem, or the only work someone has created.
Collocations and Patterns
- "唯一の友達" (ゆいいつのともだち): the only friend
- "唯一の問題" (ゆいいつのもんだい): the only problem
- "唯一の方法" (ゆいいつのほうほう): the only method
These collocations emphasize exclusivity and are common in both spoken and written Japanese.
Register and Nuance
"唯一" is neutral in formality and can be used in both casual and formal contexts. It often carries a strong emphasis on exclusivity or uniqueness.
Common Mistakes
Learners sometimes confuse "唯一" with "ただ一つ" (ただひとつ), which also means "only one." While similar, "唯一" often stresses uniqueness or exclusivity more formally, whereas "ただ一つ" can be more casual or literal in counting.
Use "唯一" when you want to emphasize that something is the sole or unique instance in a more abstract or important sense.
