Root Explanation

Dayfly → The word is formed from "day" (from Old English "dæg", meaning a period of light) and "fly" (from Old English "flēoge", meaning to move through the air). A dayfly is an insect that has a very short lifespan, typically living only for a day, hence the combination of these parts reflects its nature of flying during the day.

Memory Tip

Think of a 'day' as a period of light and 'fly' as moving through the air — a dayfly is an insect that lives and flies during the day.
