Multiple Choice

Which term means to enlarge or expand?

Dilate means to enlarge or widen something, especially an opening or passage. In medicine you’ll hear about dilating pupils or dilating blood vessels to allow more flow, which is all about making the space broader. This fits the idea of expanding, rather than measuring across (diameter), bringing substances into a cell (endocytosis), or lifting something up (elevate). The related noun form is dilation.
