sustenance

What does "sustenance" mean?
Sustenance refers to the food, drink, or other resources that are necessary for survival and the maintenance of life. The mental image is that of a fundamental source of energy, like a warm meal after a long journey or the basic nutrients that keep a living thing thriving. While it is related to "food," the word carries a more solemn, essential weight. You wouldn't typically use it for a quick snack; it is often used in the context of survival, spiritual nourishment, or the basic requirements for an organization or entity to continue functioning. It is frequently used in formal writing or when discussing the deep needs of a person or society.
