"Co" implies partnership and togetherness in many technical contexts, e.g., co-planar (located in the same plane), co-orbital (moving in the same orbit), etc.
Which prefix is the antonym of "co" whose usage reverses the meaning of the words like co-planar?
Best Answer
As suggested in the comments (thanks @Weather Vane, @Davo, @Jeff Zeitlin), there is no general rule for an antonym to "co-". It depends on the context.
In some cases, you can add more than one prefix to the word, but be aware that this can make the wording sound very technical, formal or stiff:
Many "co-" words do not have a simple antonym at all:
TLDR
There is no simple prefix like "anti" that universally does what you need.
