dilation singular

Morphology

dilation = dilate (semi-transparent) = dilate + ion

This sense is a metaphorical extension ('to expand' -> 'to expand in speech'); the relation to the base verb exists but is not an obvious nominal meaning for lower-level learners.

Etymology

Dilation also comes from the Latin root latus 'wide' and once meant 'to spread out', so a spoken or written dilation is like 'spreading' your words into a long, detailed talk.
