Catechoic

Not a language formed by the vocal cords of humans per se, the main communication system of the Catechols, is a series of clicks, whistles and hisses. This is because despite looking human the Catechols, in addition to losing their catecholamine brain chemistry, lost their larynx but not their tongues or lips. Due to its inherent lack of human phonemes, the Commonwealth has been using it as combat cant for 400 years against other human aggressors and the Furies.
