Meaning and Usage
"大半" (たいはん) means "most of" or "the majority of" something. It is used to indicate that more than half or a large portion of a group, time, or quantity is being referred to. It is a common word in both spoken and written Japanese, suitable for neutral or formal contexts.
Common Collocations
- 大半が + verb: indicates that most of the subjects perform an action (e.g., 大半が参加した - most participated).
- 大半の + noun: modifies a noun to mean "most of the..." (e.g., 大半の学生 - most students).
- 大半を + verb: used to express spending or using most of something (e.g., 大半を費やす - spend most of).
Nuances and Tips
"大半" emphasizes a majority but does not specify an exact percentage. It is stronger than "少し" (a little) but less precise than exact fractions. It is often used when the speaker wants to express a general majority without needing exact numbers.
Avoid confusing "大半" with "ほとんど" which can mean "almost all" or "nearly" and sometimes implies a higher percentage than "大半." Use "大半" when you want to express a clear majority but not necessarily almost all.
Formality
"大半" is neutral and can be used in both casual and formal situations, including news reports, academic writing, and everyday conversation.
