Why is it that an object can accelerate at a constant speed but not at a constatnt velocity

An object can accelerate while traveling at constant speed but not at constant velocity. This is because acceleration is a measure of the change in velocity over time. Speed is a scalar quantity with magnitude but not direction while velocity is a vector quantity with both magnitude and direction.
