atrimenensia
noun
A piercing solitude when you lose someone dear, only to find the world around you maintains its rhythm, unfazed and unyielding to the weight of your grief, as if an essential piece of your heart is missing while others seem whole.
Combining Latin 'ater' (dark, black) with 'imensio' (dimension, measure), this word suggests the dark, immeasurable solitude experienced in mourning. Pronounced "ah-tree-men-EN-see-ah"
