Morphology
The compound is compositionally built: 'fly' (move through the air) + 'ash' (residue from burning) yields ash that is carried or suspended in the air. Although a technical term, its meaning is directly inferable from the constituent words and common cross-linguistic patterns for ‘‘airborne’’ + material, so a B1 learner who knows both words can understand it.
Etymology
The noun fly ash comes from the simple image of tiny ash bits that fly in the air when fuel is burned, so the term means 'fine particles of ash carried into the air'.
