JLPT: N4
School Grade: 2nd (7 years old)
This character is a combination of 糸 thread (here meaning silk thread) and 氏 family/clan. In this context 氏 is working phonetically to express “smooth,” so this character originally meant “smooth silk,” and more generally “smooth cloth.” Because cloth was used as writing material, 紙 came to mean “writing material,” and eventually “paper.”
