Understanding 機能 (きのう)
The word 機能 refers to a function or capability of a device, system, or even a biological organ. It is commonly used in both technical and everyday contexts to describe what something can do or how it operates.
Common Uses
- Describing features of electronic devices or software (e.g., スマートフォンの機能).
- Talking about biological functions, such as brain or organ functions.
- Referring to specific capabilities within applications or machines.
Collocations and Patterns

- 機能を持つ: to possess a function.

Usage Notes
When using 機能, the focus is on the practical or operational aspect of something. It is more formal and technical than words like 役割 (role). Learners sometimes confuse 機能 with 作用, but 作用 often implies a physical or chemical effect, while 機能 is about purpose or capability.
