3: Output of 1 with input of 2

punishment –> punishmenten

argument –> argumenten

assignment –> assignementen

With the outcome punishmenten, arguementen, and assignmenten they are clearly words that are not well formed nor are they already existing words. The two affixes that i had chosen dont go hand in hand together, like most, but some words are always an exception. A working two affixes would be carelessness and apprehensiveness. But analyzing my chosen ones dont qualify. This process seems to work with words that go from noun to noun changing. It does not seem to work with noun to verb to noun changing words as the meaning is lost even though it can be a word.
