maneuverable
Able to change direction or position easily and quickly.
Maneuverable describes something that can change direction or position easily and quickly. A small sports car is more maneuverable than a large truck because it can zip around corners and squeeze into tight parking spaces. A kayak is more maneuverable than an ocean liner because a paddler can spin it around or navigate through narrow channels with just a few strokes.
In battle, generals maneuver their troops to gain advantages. In everyday life, you might maneuver through a crowded hallway at school or maneuver a shopping cart around other customers.
Being maneuverable matters most when space is tight or situations change quickly. Fighter jets need to be highly maneuverable to respond instantly in the air. Soccer players work on their footwork to stay maneuverable around defenders. Even furniture can be maneuverable: a desk on wheels is easier to reposition than one that's bolted to the floor.
The opposite would be something cumbersome or unwieldy, like trying to carry a giant piece of plywood on a windy day. When something is maneuverable, you have the control and flexibility to respond to whatever comes your way.
