Did you know that the rectrix feathers help birds change direction while flying?

Really? I had no idea they played such an important role.

Yeah, it's fascinating how much control they have with those feathers.

Root Explanation

Rectrix → It is formed from "rectus" (meaning straight or right) and the suffix "-trix" (meaning a female agent or doer). The word "rectrix" refers to a female who guides or directs, often used in the context of birds to describe the tail feathers that help in steering.

Memory Tip

Think of 'straight' ('rectus') and a female 'doer' ('-trix') — a rectrix is someone who guides or directs, much like how tail feathers help a bird steer.
