n.
the state of not knowing how you really feel about something, which forces you to sift through clues hidden in your own behavior, as if you were some other person—noticing a twist of acid in your voice, an obscene amount of effort you put into something trifling, or an inexplicable weight on your shoulders that makes it difficult to get out of bed.
Ancient Greek ἄγνωστος (ágnōstos), not knowing + διάθεσις (diáthesis), condition, mood. Pronounced “ag-nos-thee-zhuh.”
