Outside of Kalos, it was once believed to be an iron law of language that no pokemon's name – defined by the phonemes it uses to communicate, as transcribed into the Unown alphabet – could exceed ten letters in length. The magic of the Unown is remarkable, certain pokemon have used telepathy to mimic human speech, and some Chatot and scattered reports of a single Meowth have claimed to develop the full complement of sounds associated with human language; any more than that was said to be the sole province of Man. In Johto, Feraligatr was even given a questionable spelling to adhere to this law; Kalosian observers have often transcribed the pokemon's name as Feraligator, and few can credibly argue that they are wrong to do so.
Yet despite all foreign efforts, there is simply no way to do the same with Fletchinder, who enunciates its syllables so clearly that its eleven-letter sound can not be mistaken for anything else. This discovery caused an immense stir in the field of linguistics, for it caused many to question whether a theoretical barrier to the length of pokemon names exists whatsoever – and by association, the questioning of many other principles, such as whether every Unown has yet been discovered.
Human names – long similarly restricted, so as not to proclaim one's self as superior to their pokemon - also possess a limit in Kalos, but the number they use is twelve, one higher than Fletchinder and two higher than the world knew before its discovery. Whether this is set slightly higher because of some extinct creature with an even longer name than the Fletchinder, or because the people of Kalos, although loathing overly cumbersome names, consider it a right to have a longer name than any pokemon, remains the subject of heated dispute.
