The word 制度 is a compound word formed from the kanji 制 (sei) and 度 (do). 制 (sei) means "system," "rule," or "regulation," while 度 (do) means "degree," "measure," or "system." Therefore, 制度 collectively signifies a system or set of rules. The origin of this word is from Chinese characters that were adopted into the Japanese language.
