saturate
This term describes a state of absolute fullness where a threshold has been reached and no further intake is possible. In a physical sense, it evokes the image of a sponge or soil that cannot hold another drop of water, shifting from a state of absorption to one of overflow. In economic or social contexts, the word carries a connotation of stagnation or peak capacity. When a market is saturated, it implies that growth has ceased because every potential customer already possesses the product, creating a ceiling that prevents further expansion.
