Morphology
dilatation = dilate (transparent) = dilat + ation
Learners who know the verb 'dilate' can readily infer 'dilatation' as the noun denoting the process or result formed by the productive suffix '-ation'.
Etymology
Dilatation comes from Latin parts di- meaning 'apart' and latus meaning 'wide', so it originally meant 'making wide'. So, dilatation is the process of something becoming 'wider' or more open, especially in the body.
