Hi Jim,
this is true of any word in another language, and quite a few of the ones in ours. My reaction was rather similar to yours - but it's really a matter of degree. If I want to use, in a German text, the notion corresponding to gobbledegook, and need a full paragraph to render it, the effect is all but gone. Btw I suspect German has no word for gobbledegook because this would cover too much of it..
