Morphology

structureless = structure (transparent) = structure + less

Standard derivation: 'structure' + '-less' denotes absence of an organized internal structure.

Etymology

Structureless comes from structure ('arrangement' or the way parts are built together, as in construct) plus -less ('without'). So in science it means 'without a regular internal arrangement', like glass or a shape that shows no clear pattern.
