means The quality of being shaped by personal feelings, tastes, and perspectives rather than by external facts — how a thing looks from inside one particular mind.

from From Latin subiectus, 'thrown under' or 'placed beneath' (sub-, 'under,' plus iacere, 'to throw') — the same root that gives us 'subject.' Originally a grammatical and philosophical 'subject' was that which lies under, the thing doing the experiencing. The abstract noun 'subjectivity' came later through philosophy, hardening into its modern sense of the personal and partial as thinkers wrestled with how the knowing self colors everything it knows.
