It's relatively common to have dictionaries of foreign words here in Slovakia, and in the front of one I found common prefixes and suffixes. This is something I was dying for this summer, and so I'll share a bit of it now:
|a-, an-||ne-, bez-,|
|ex-||bývalý, von, preč|
|co-, com-, con-||s-, zo-, spolu-|
The point of all of this is that now I can more effectively make up words in Slovak!
