4-dimensional = dimensional (transparent) = 4 + dimension + al
The numeral '4' transparently modifies the adjective 'dimensional' to indicate having four dimensions.
Etymology
4-Dimensional comes from the number four and dimension, where dimension means a 'direction' or 'measure', like in the familiar '3D' or 'three-dimensional' things. So a 4-dimensional object has 'four directions' to move or measure — usually the three directions of space plus time, which is why people call space and time together 4-dimensional.
