Morphology
dilate = dilat + ate
Formed from the Latinate combining form 'dilat-' + the verb-forming suffix '-ate'; the meaning 'become wider' aligns with the historical stem but the stem is not a standalone English word, so learners cannot fully deduce it from common English bases.
Etymology
The word dilate comes from the Latin parts di- ('apart') and latus ('wide'), so it originally meant to 'make wide'. That's why to dilate is to become wider or more open, as when your pupils dilate in the dark.
