mysterious => mysteriosity
ferrous => ferrosity
obvious => obviosity

Another class of common construction uses the suffix `-itude' to
abstract a quality from just about any adjective or noun. This usage

same abstraction through `-iness' or `-ingness'. Thus:

win => winnitude (a common exclamation)
loss => lossitude
cruft => cruftitude
lame => lameitude

Some hackers cheerfully reverse this transformation; they argue, for
example, that the horizontal degree lines on a globe ought to be
called `lats' -- after all, they're measuring latitude!

Also, note that all nouns can be verbed. E.g.: "All nouns can be
verbed", "I'll mouse it up", "Hang on while I clipboard it over", "I'm
grepping the files". English as a whole is already heading in this
direction (towards pure-positional grammar like Chinese); hackers are
simply a bit ahead of the curve.

The suffix "-full" can also be applied in generalized and fanciful
ways, as in "As soon as you have more than one cachefull of data, the
