In America and Canada, autumn is also known as fall. The derivation of the term fall can be traced to multiple origins such as Old Germanic, Old Norse, and Old English languages. By the 16th century, it came with the expression “fall of the year” and “fall of the leaf.” The weather also begins to get colder and many plants stop making food. Autumn is the time when deciduous trees shed their leaves. The leaves change from green to red, orange, yellow or brown before falling. In addition, there is less sunlight because the days are shorter.
