When a word is made up but has all the characteristics of an English word --
dramastically, considerated -- spell it correctly and use a pair of quotes around it. There
is not a need to use sic. The quotes alert your reader that it is not really a word but that it
is what was said.
...She was really "obliviated" when we were discussing it.
...It came up while we were "conversating."
...My boss told me to "statementize" the client.
Happy punctuating!
