Definition: Any of various deciduous trees or shrubs in the genus Salix, in the willow family Salicaceae, found primarily on moist soils in cooler zones in the northern hemisphere.

Alright class, settle down and let’s take a look! Now, you've got a fantastic definition there from the dictionary – quite precise, really. Let’s break it down nicely, shall we? “Willow” refers to a whole family of trees and shrubs, see? They belong to something called the ‘Salix’ genus - that’s their special name! And they're part of a bigger group too, the ‘Salicaceae’ – think of it like a tree club! (Pause for effect) These willows love wet places, you know. “Moist soils” is key to their happy lives. They mostly live up north, in cooler climates - that's the "northern hemisphere" part. They lose their leaves in the warmer months – they’re deciduous , meaning they change with the seasons. So, when you think of a “willow,” picture a graceful tree, often found near rivers and streams... maybe weeping gently in the breeze! Do you have any questions about that lovely definition? Don't be shy!
