PS :
There are different names and meanings of 合体字 , such as 合成字、合字、合文 .... etc. basicaally，they are the character formed by combining independent characters or the parts of characters

( 上 ) : 他 = he ( 人+也 )、她 = she ( 女+也 )、它 = it ( things or animals )
( 下 ) : 祂 = He ( god , 示 +也 )、【 忚 】( read as xī or liě ) 、牠 = it ( animals , 牛 + 也 )
● We can notice 也 is the common part of those characters，and there is a different character 它 ! What is the meaning of 它 ?
The character 它 shares the same origin of 虫 and 也 ，all are the image of 蛇 ( snake ) ，and 虵 ( shé ，虫 + 也 ) is a variant character of 【 蛇 】( 虫 + 它 ) .
● In the eyes of the ancients, the snake was " the opposite of humankind " , so 它 was used to refer to everything other than humans , and 也 is a variant of 它 !
PS :
忚 = 心 + 也 ( heart + snake ) = xī ( deception ; contempt ) ； or liě ( the heart does not desire )
