A while ago on Zompist’s conlang forum, we came up with a quick cypher we dubbed “Pig Elvish”. It’s fairly easy for the trained eye to read, but to the uninitiated it looks an awful lot like Tolkein’s Elvish–Sindarin, IMO, but some people think Quenya.
For example, the above text would read as follows:
Aen hilewa goáen noen Ompístzi’sén onlangcú orumfi, ewen ameco puen ithwo áen uiccqa yphercë; ewen ubbéddi “Igpen Lvisheo”. Tien’sen airlyfo ásyeu orfen heten rainedtu yeéen oten eadra, utben oten heten ninitiatedue tien oócslo naen wfúlaa otlen icela Olkeinte’s lvishei–Indarínáo, IMO, útben omésu eoplepa hinctë Uenyaqu.
The algorhythm is simple: take the first letter and move it to the end. If the word is three letters or fewer, append “en”. If it’s four or more, append a random vowel. Mark any final Es with a diaresis (or umlaut, if you insist), and add acute accents at will. Change all Ks to C.
In any case, the posts to Zompist’s boards seem to have gone away, so I wanted to preserve the cypher. It falls down when presented with very long words, and is slightly lossy in that there’s no way for a simple search-and-replace to determine if this particular C should be turned into a K, but as cyphers go it’s easier to read than rot13.
