It is motion that is confined a single direction. That being said you can also expand it to include motion along a single line such as when a bead moves along a curved wire.
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.

Circular motion is a type of two-dimensional motion that is not always projectile motion. In circular motion, such as a car driving around a curve or a satellite orbiting a planet, the object is constantly changing its direction without necessarily being launched upwards. This motion can involve acceleration due to the changes in velocity direction.
One dimensional motion occurs along a straight line, typically represented by a single axis. It involves movement in either the positive or negative direction on that line. Velocity and acceleration are scalar quantities in one dimensional motion.

A motion along straight line is called rectilinear motion. In general, it need not be one - dimensional; it can take place in a two dimensional plane or in three dimensional space. But, it is always possible that rectilinear motion be treated as one dimensional motion, by suitably orienting axes of the coordinate system.

One-dimensional motion is motion in a straight line.

2 dimensional motion refers to motion occurring in a plane, where an object can move horizontally and vertically. This type of motion can be described using both x and y coordinates to track the position of the object. Examples include objects moving in a projectile motion or in circular motion.
Going round in circles!
If only one quadrant of a body out od three quadrant of the position change than motion of the body is called one Dimentional motion. Ex-MOtion of a body in a straight line ,path,vertical motion under gravity etc...
In two-dimensional motion that is not projectile motion, the object may have acceleration even if it is not accelerating overall. This is because the object's velocity can change direction in two dimensions without necessarily changing its magnitude, leading to acceleration along curved paths. Projectile motion, on the other hand, involves acceleration only in the vertical direction due to gravity while the horizontal velocity remains constant.
