 The Al Bhed speak their own ' language ' which is really just a substitution cipher of English , a system of transposing certain letters for others ; however , within the game world , it is intended to be an actual language . The original Japanese version of the cipher uses the syllable @-@ based kana system of writing where each symbol represents a combination of " consonant + vowel " or simply a vowel . Certain keywords are not translated into Al Bhed in the game , to give the impression of use of loanwords compared to modern foreign languages . Most keywords are proper nouns , but some common nouns also are not translated , such as " fiend " ( e.g. Y fiend ! Eh risyh teckieca ! [ A fiend ! In human disguise ! ] ) . Alexander Smith , decided to " map common phonemes in English to common phonemes in Welsh " and gave preference to Welsh pronunciations , but had to work with new diphthongs to maintain consistency in the Al Bhed language .
