the word 'subsistence' originates from the latin verb 'subsistere', which combines 'sub-' (under) and 'sistere' (to stand). its core literal meaning was 'to stand firm, to hold one's ground, to remain'. this evolved into the sense of maintaining oneself, of withstanding or persisting. over time, through late latin and old french, the abstract noun 'subsistence' came to specifically denote the minimal means by which one maintains existence, the state of just managing to stay alive or in being, capturing the idea of barely holding one's position under the pressures of life.
