Understanding 性能
The word 性能 (せいのう) refers to the performance, ability, or capability of a device, machine, or system. It is commonly used when discussing technology, vehicles, electronics, and other equipment to describe how well something functions.
Common Contexts
You will often hear 性能 used in contexts like comparing cars, computers, smartphones, or appliances. It emphasizes the practical effectiveness or technical specifications that determine how well the item performs.
Typical Collocations
- 性能が良い／悪い: good/bad performance
- 性能を比較する: to compare performance
- 性能向上: performance improvement
These phrases are useful when discussing upgrades, reviews, or technical evaluations.
Usage Notes
性能 is a formal and technical term, suitable for both spoken and written language, especially in professional or academic contexts. It is not used for human abilities but rather for objects or systems. Avoid confusing 性能 with 能力 (のうりょく), which refers to human ability or talent.
Common Mistake
Learners sometimes confuse 性能 with 能力. Remember, 性能 is about how well a machine or device works, not about personal skills or intelligence.
