The Etymology of Gnathology and Gaku-kougou-gaku

Abstract

GNATHOLOGY and GAKU-KOUGOU-GAKU (its Japanese translation) are traced to their origin.
GNATHOLOGY is composed of the prefix GNATH, the conjunction O and the suffix LOGY. GNATH comes from GNATHOS, which in Old Greek means jaw. O is a conjunction. LOGY comes from LOGIA in Latin and means doctrine, theory or science. Stallard H. is generally credited with composing the word Gnathology.
GAKU-KOUGOU-GAKU is made up of GAKU+KOUGOU+GAKU. GAKU means jaw in Japanese, KOUGOU means occlusion, and the final GAKU is the same as LOGY, meaning doctrine, theory or science. The word GAKU-KOUGOU-GAKU was thought up by the author.
GAKU-KOUGOU-GAKU is written _??_ _??_ _??_ _??_ in Chinese characters, which is the official term for Gnathology in Japan and other countries of the International Academy of Gnathology Asian Section.
