The kanji 世 generally represents the concept of "world," "generation," or "age." It can refer to the present world, the passage of time, or a period of history. It often implies a social or human context.

⚫︎世界 (sekai) Translation: World ⚫︎世の中 (yononaka) Translation: The world; society; the times ⚫︎世代 (sedai) Translation: Generation

The kanji 世 is pictophonetic. It combines the radical 艹 (grass, plant) on top with a component that depicts a "three" or a "threesome" (like the number of stages in life or an epoch of time). The three horizontal lines are simplified from three bundles of something, perhaps representing an aggregate or a whole. The combination suggests a passing of time that accumulates from one generation to the next, like three (or many) bundles.
