Morphology

four-dimensional = four + dimensional (transparent) = four + dimension + al

The meaning follows directly from the numeral 'four' plus the adjective 'dimensional', so the whole word is compositionally interpretable.

Etymology

Four-dimensional is made of four and dimension, and dimension comes from a word meaning 'measure'. So four-dimensional means 'having four measures', which usually means the three directions of space plus time as the fourth.
