a lifeless [body/person/animal]
よくある間違い：
Learners sometimes use "lifeless" instead of "dead" in everyday speech. "Dead" is more common and natural in most casual contexts (e.g., "My phone is dead," not "My phone is lifeless"). "Lifeless" is often used in more serious, descriptive, or written language, especially for bodies.

用法パターン：
a lifeless [event/performance/voice/room]
よくある間違い：
Learners may confuse "lifeless" with "boring" or "tired." "Lifeless" usually describes the quality of something (a performance, voice, party) rather than a temporary feeling. We say "I feel tired" more often than "I feel lifeless."

用法パターン：
a lifeless [place/landscape/planet/object]

Learners might mix this sense with the figurative "boring" sense. If you mean "not interesting," use sense 2; if you mean "no living things are there," use this sense. In scientific or nature contexts, this environmental sense is usually intended.

inanimate (More technical/formal; describes objects that are not alive and do not move by themselves.)
