Not true. Medical and Engineering use alot of Latin and Greek terminology. Chefs and cooks use foreign terminology. The explanations are in your mother tongue but not necessarily the terminology.
Who is going to translate the Japanese meaning of Shomen Uchi Irimi Nage from Japanese to Inuktitut? After I learn my Aikido in Inuktitut, who am I going to teach it to, only people who speak Inuktitut?
By not using a common language for terminology ( not necessarily the explanations) then you are limiting the pool of possible people to learn from, those that use terminology in your mother tongue.
