幽体

1. Origins, structure, and basic meaning

• Basic usage: It denotes a spirit body separated from the physical body in fantasy, as in 幽体となって体を離れる.

2. Common pitfalls and similar expressions

• Scope and context
  • It is a supernatural term rather than a medical one and, unlike a bare 魂, may be represented as a body-like form.
