noun
- A conlang that has components from numerous languages but is poorly put together.“[Disclaimer: I've never actually made a conlang this way yet -- this is just what I do with my *current* conlang by picking what I figure would sound like a good ancestor-lang root and "mutating" it -- so don't blame me if it produces a frankenlang :-P]”
