Morphology

preexperimental = experimental (semi-transparent) = pre + experiment + al

The word is formed by prefixing 'pre-' to 'experimental'; however, in research contexts 'preexperimental' denotes a specific class of designs (lacking full experimental controls), so the exact methodological nuance is not fully inferable without disciplinary knowledge.

Etymology

Preexperimental is made of pre- meaning 'before' as in preview, and experimental meaning 'relating to an experiment'. So a preexperimental design is done before a full experiment and often does not have full experimental control, for example no control group.
