Learn one Chinese Character a day - 牵 | 牽

Our character today 牵 is also related to 牛. Upper part of 牵 is kind of ambiguous. Its Traditional version 牽 provides more information, which contains 玄,  and 牛. As what we learnt with 丝 (https://xiongzou.blogspot.com/2016/01/learn-one-chinese-character-day_6.html), lower part of 玄 is related to silk: .  That is all we can get so far, ancient scripts of 牵 would help us as usual: (image taken from http://vividict.com)

Evolution history of 牵

Oracle script is quite obvious now, rope () is tied to a kind of nostril ring () to lead the buffalo ().

牵牛

Seal Script represented the idea clearer: a hand () use a rope () to lead a buffalo ().

That is the original meaning of 牵 | 牽 - "lead along a buffalo".

Getting back to Tradition character 牽, which is 玄,  and 牛. now we can guess that could be ox yoke.

Ox Yoke

So 牵 | 牽 is used to mean lead along, for example 牵手.

Since 牵 | 牽 contains the representation of connecting with a buffalo using a rope. thus 牵 | 牽 is also extended to mean "connected to / connected with". For example 牵连.

That is all, let us enjoy a Chinese calligraphy with 牵 | 牽 inside:

天街夜色凉如水；
卧看牵牛织女星。
