Our character today is 亦. We might not know how it was created now, but can see its likeness after knowing its ancient scripts (image taken from http://vividict.com/):
|evolution history of 亦|
What does it mean here? I guess Chinese ancestors was trying to draw the movements of a person, something demonstrated as below:
So the original meaning of 亦 is a person who is walking. If we look back at 亦 now, does not it still look like a walking person?
Since everybody walks in the same way, thus 亦 contains the meaning of the same, as well or too. for example 不亦乐乎.
And while we are walking, our hands and legs keep doing the same pattern, which can conclude to the meaning of the same as well.
Kids learn and copy the way adult walks, 亦 thus contains a subtle meaning of copy to do the same, for example 亦步亦趋.
That is all for 亦, time to enjoy Chinese calligraphy with 亦 inside:
