subsistence
Having just enough to survive, with nothing extra.
Subsistence means having just enough of the basic necessities to survive: food, water, and shelter. When a family lives at the subsistence level, they have exactly what they need to stay alive, but nothing extra. There's no money for luxuries, treats, or even small comforts.
Throughout most of human history, people lived by subsistence farming, growing only enough crops to feed their own families. A bad harvest could mean disaster because there was no surplus stored away. Today, subsistence farmers still exist in many parts of the world, working small plots of land and eating what they grow rather than selling it for profit.
The word captures a difficult reality: when you're at subsistence level, you're getting by day to day, but you're not thriving or building toward something better. A subsistence wage is just barely enough money to pay for food and basic shelter. A subsistence diet provides the minimum calories needed to function, but might lack variety or proper nutrition.
Think of subsistence as the baseline of survival. It's the difference between having a full refrigerator with snacks and choices, versus having just enough rice and beans to fill your stomach. Communities working their way out of subsistence conditions are moving from merely surviving to building stable, secure lives.
