dirification (noun) or to dirify (verb).
A relatively new and generally unknown word (there's really no definition I can find), but credit goes to the developer community of the Movable Type blog software for bringing it to my attention. In its original use, it describes the conversion of space characters to either hyphens or underscores. It could have a more general meaning.
I suspect the creator of this word has either forgotten the words "derivation" (noun), "to derive" (verb), or perhaps found them inadequate to describe the process of character conversions. Add this to the list of words representing and erosion or evolution of the english language. How long will it be before the Oxford dictionary, or wikitionary, legitimizes its use?
