Morphology
The phrase is compositionally built from 'white' (a color) + 'matter' (a substance), so a learner who knows those words can infer it refers to a pale/white substance — in context, the substance in the brain or spinal cord. Although the full technical details (myelinated nerve fibers, signal transmission) are specialized, the core referent is directly derivable from the constituents.
Etymology
White matter is named for how it looks: groups of nerve fibers are covered in a fatty, pale layer so this part of the brain looks white next to the darker 'grey matter'. Because these groups help 'send signals' between brain areas, the term now means the brain tissue that moves messages around.
