The word 重要性 is a compound word. 重要 (juuyou) means "important" or "significant," derived from the kanji 重 (jū/omo-i) which has a meaning of "heavy" or "serious" and 要 (you) meaning "need" or "essential." The suffix 性 (sei) is a suffix that turns adjectives and adjectival nouns into nouns, and it conveys the concept of "quality," "nature," or "state" of being. Therefore, 重要性 combines the idea of something being "important" with the "state" or "quality" of being important.
