Quite often we need separating, as happens when two things are stuck together and want them apart, etc.
The separation picto is just a vertical straight line that separates two pictos or concepts:
I am sad (because ) I am separated from my family:
We (a man and a woman) were together but at present we are separated (notice both tenses):
The verb Separate can be picted depending on the case:
Separate (one thing from others ):
Disengage, disconnect, etc:
