I read an article about how eosinophils play a role in allergic reactions.

Root Explanation

Eosinophil is formed from "eos" (from Greek Ἠώς, meaning dawn or rosy) and "-philos" (from Greek φίλος, meaning loving or fond of). The term refers to a type of white blood cell that has an affinity for the dye eosin, which gives it a rosy appearance under a microscope.

Memory Tip

Think of 'eos' meaning dawn or rosy, which helps you remember that eosinophils are the cells that love the rosy dye eosin.
