Morphology
investigational = investigation (semi-transparent) = investigat + ion + al
The form is built from 'investigation' plus '-al', but the specialized scientific and medical sense 'experimental or being tested' is less directly predictable for learners.
Etymology
Investigational comes from investigate, based on a Latin root meaning 'to follow a trace', like the word vestige. So an investigational treatment or test is one under study where researchers 'follow the traces' to see if it works.
