Understanding 神経 (しんけい)
The word 神経 primarily refers to "nerve" in both the physical and figurative sense. Physically, it means the nerves in the body, but it is often used metaphorically to describe sensitivity, tension, or mental strain.
Common Uses
- Describing physical or mental sensitivity: 神経が鋭い (sharp nerves) means someone is very sensitive or perceptive.
- Expressing mental effort or tension: 神経を使う means to be careful or to exert mental effort, often leading to fatigue.
- Describing stress or tension: 神経が切れる implies a breaking point of nerves, indicating extreme stress or frustration.
Collocations and Patterns
- 神経が鋭い: to be sensitive or perceptive.
- 神経を使う: to use one's nerves; to be careful or stressed.
- 神経が切れる: to lose patience or become extremely stressed.
Usage Notes
When using 神経 in conversation, it often conveys a sense of mental or emotional sensitivity rather than just the physical nerve. Be careful not to confuse 神経が鋭い (sensitive) with simply being nervous. Also, 神経を使う is a common phrase to express the effort of paying close attention or being cautious.
Common Mistake
Learners sometimes confuse 神経 with 感覚 (sense, feeling). 神経 focuses more on the nervous system or mental sensitivity, while 感覚 refers to sensory perception more broadly.
