Homonym: Level (Stage)
A "level" is a tool used in construction and carpentry to determine if a surface is horizontal (flat) or vertical (upright). It typically consists of a long, straight bar with a liquid-filled vial containing an air bubble. When the bubble is centered between the marked lines in the vial, the surface is considered level.
In a broader context, "level" can refer to a stage or degree of something, such as skill or achievement. For example, in video games, players often progress through different levels that represent increasing difficulty or complexity.
