dwindle

This verb describes a slow, steady decline rather than a sudden drop. It evokes a sense of gradual depletion or fading away, often used when discussing resources, hopes, or populations that are shrinking over time. Because it implies a process of attrition, it is frequently paired with words like "gradually" or "steadily." It carries a slightly melancholic or worrying connotation, suggesting a loss of viability or strength.
