Dear Michael:
I have a German dictionary. It seems that there are two
groups of words:
(1) Die Verwandlung (noun); verwandeln (verb). [Used by
Marx]
(2) Three words which are synonymous:
a. Die Transformation (noun); transformieren (verb)
b. Die Umformung (noun); umformen (verb)
c. Die Umwandlung (noun); umwandeln (verb)
I think that these are additional "weapons" to bother both,
your partner and Chris Arthur,
Alejandro
