Paragraph:

 The origin of deciduous is the latin word cadere, "to fall." Its literal meaning is "tending to fall" or "temporary." Just think of leaves falling in autumn. If you want to appear even more knowledgeable: coniferous trees are trees with cones, like pine trees with pine cones. These trees do not shed their leaves like deciduous trees.
