Understeer is a term for a car handling condition in which during cornering the circular path of the vehicle’s motion is of a greater radius than the circle indicated by the direction its wheels are pointed. The effect is opposite to that of oversteer. In simpler words understeer is the condition in which the vehicle does not follow the trajectory the driver is trying to impose while taking the corner because the effective slip angle at the front is larger than that at the rear, instead following a less curved trajectory. Understeer covers several different phenomena; in particular, there is a big difference between linear range understeer, typically between 0 and 0.4g, and limit handling understeer, which is at higher lateral accelerations, and is what racing drivers reference when they use the term.
