Interdisciplinary Diction Sprawl

I find that one of the problems with my life experience is that I have tried to learn a lot about a lot of things.  I genuinely want to be a life-long student.  The problem lies in the fact that some fields of study have specific vocabulary that conveys a similar concept in another field.  And if I’ve learned the concept in one field then I accidentally slip in the wrong word.  A prime example that happens to me all of the time is using the word fidelity.

I use fidelity to describe a slew of things that probably should never have that term applied to them.  Photography uses clarity, focus, sharpness and other words, but usually not fidelity – however just like my ‘hi-fi’ stereo system I like high fidelity images.  I also like to think of coffee grounds as maturing in the water instead of brewing.  Why?  Because I’m goofy like that.

What words do you interwingle [which is a made-up word from the internet to convey a usefulness in mixing data from multiple sources]?
