Why do prefixes such as com, con, col and cor have the same meaning?

First of all, because these prefixes are derived from the Latin preposition cum, which means "with" and has the same meaning as * * * *, another reason is that these prefixes are artificially specified, and there is no special reason, that is, the established rules when creating languages. For example:

1, com: ordinary * * * * Yes, the community * * * enjoys it.

2. Disadvantages: combine * * * * with fighting and fighting.

3.col: cooperation, colleagues and colleagues

4.cor: correlation * * * * homology
