Unfortunatly due to the limitations of lingo-jam (Which can easily be fixed (wink wink developer/s)) You have to type the suffixes and prefixes as separate words and delete the spaces post-translate. For 's you have to type gs, in- iin, be- gbe.
Punctuation marks (! . ?) Have to be separate as well for they are also considered words and have phonetic equivalents. They are separate from the other words.
