Subir vs. entrar
While both subir and entrar can sometimes be translated as to get in or to enter, they describe fundamentally different actions. The key difference lies in the direction of the movement: subir implies moving upwards, while entrar implies moving inwards.
Subir
A1The verb subir primarily means to go up, to ascend, or to climb. When used for vehicles like cars, buses, or trains, it means to get on or to get in because you typically have to step up to board them. The central idea is always an upward movement.

Entrar
A1The verb entrar means to enter, to go in, or to come in. It describes the action of moving from an outside space to an inside space, such as a room, building, or city. It focuses on crossing a threshold, not on the direction of elevation.
