A fictitious force, also called a pseudo force, d'Alembert force or inertial force, is an apparent force that acts on all masses in a non-inertial frame of reference, such as a rotating reference frame.

A pseudo force arises when a frame of reference is accelerating compared to a non-accelerating frame. As a frame can accelerate in any arbitrary way, so can fictitious forces be as arbitrary (but only in direct response to the acceleration of the frame). However, four fictitious forces are defined for frames accelerated in commonly occurring ways: one caused by any relative acceleration of the origin in a straight line (rectilinear acceleration), two caused by any rotation (centrifugal force and Coriolis force) and a fourth, called the Euler force, caused by a variable rate of rotation, should that occur.

in simple words we can state a pseudo force as an imaginary force acting on a body when viewed from a non inertial frame of reference. and a pseudo force is used to make newtons laws applicable in such frames

force experieced by an body in an accelerated frame of reference in  the direction opposite to that of the motion of frame eg aboy in a moving bus
