sin·an·i·mous
/sɪnˈænɪməs/
adjective
1. Lacking the essential spirit or vital force of life; profoundly hollow.
2. Characterized by a state of being ‘without soul’; specifically referring to a person or object that remains physically present but is spiritually or emotionally vacant.

Etymology
From the Latin sine (“without”) + animus (“soul, mind, breath of life”). Unlike inanimate (which describes objects that have never possessed life), sinanimous implies a state of deprivation or the active absence of a spirit that ought to be there.

Usage Note
While inanimate is a clinical or scientific term for non-living matter (e.g., rocks, water), sinanimous is a literary or philosophical term used to describe a haunting or unnatural lack of vitality in things that typically possess it (e.g., a crowd, a home, or a human gaze).
“The abandoned cathedral felt sinanimus, as if the very air had forgotten how to carry sound.”
