I heard the doctor used a dilator during the procedure.

It helps to widen a passage, like in certain surgeries.

That makes sense — I guess it's essential for some medical tasks.

Root Explanation

Dilator → It is formed from "di-" (meaning apart) and "lator" (from "latus", meaning to carry or bear). The word "dilator" refers to something that carries or brings apart, often used in a medical context to describe a device that expands or opens an area.

Memory Tip

Think of something that 'carries apart' — 'di-' means apart, and 'lator' relates to carrying. This helps you remember that a dilator is used to open or expand an area.
