@kaptenkloun one difference between "jebać" and "pierdolić" would be "z"/"s" prefix. No such thing as "sjebać", and no such thing as "zpierdolić".

Granted, this is a bit "cheating" on my part, as the "s" prefix for "pierdolić" does what "z" prefix for "jebać" does, roughly.

There are also slight nuances in meaning between "-jebać" words and "-pierdolić" words, sometimes.

But there are other swear word roots that do have considerably different meanings with the ~same prefixes. 🙂
