Langwidge is a rank-2 temperament whose generator is ~~an interval close to the~~ perfect fifth, and it is constructed with purpose of ~~exploiting a loophole involving enharmonicity in Western music theory~~.

Langwidge is a rank-2 temperament whose generator is a perfect fifth, and it is constructed with purpose of spelling the minor triad wrong.

The name "langwidge" originates from Adam Neely's video "''Is Cb The Same Note as B?''", where he mentions that there's "nothing technically incorrect about spelling the word language as "langwidge", but word structure-wise the information is different<ref>[https://www.youtube.com/watch?v=SZftrA-aCa4&t=210s&pp=ygUYSXMgQyMgdGhlIHNhbWUgbm90ZSBhcyBC Is Cb the same note as B?] by Adam Neely</ref> because it's not spelled right. In addition, he goes on to mention about how the "order of spelling in Western music theory is sacrosanct"~~. Therefore, langwidge temperament is constructed with the purpose of defying the Western spelling~~.

In addition, he goes on to mention about how the "order of spelling in Western music theory is sacrosanct".

In this case, the temperament's generator is ~~a slightly flat fifth~~, 9 of which yield [[38/1]], meaning ~~that~~ when octave-reduced, this would require spelling ~~root-3rd-P5 triad with~~ 19:16 as C-D#-E and not as C-Eb-E, producing this peculiar violation of standard Western music theory.

In this case, the temperament's generator is [[3/2]], 9 of which yield [[38/1]], meaning [[19/16]] is mapped to C-D#. This means, when octave-reduced, this would require spelling the 16:19:24 triad as C-D#-E and not as C-Eb-E, producing this peculiar violation of standard Western music theory.

~~Since [[355edo]] and [[722edo]] are good at supporting this kind of mapping, and they're~~ also good at approximating [[17/16]], this makes 355 & 722 2.7.19 subgroup the most natural and simplest way to tune this temperament, producing a rank-2 temperament associated with the {{monzo|-109 0 0 0 0 0 9 17}} comma. This means that the generator fifth in question is mapped to [[6137/4096]], and nine of them make [[38/1]], meaning [[19/16]] is mapped to C-D#. For the purest 19th harmonic, 722edo is the best due to it being a convergent to log2(19/16). The generator fifth is flat of pure [[3/2]] by [[6144/6137]].
