Etymology

Compound of 弗 (futsu, used phonetically) +‎ 素 (so, “chemical element”). First used by Morisaburō Ichikawa in Rika Nikki (1872).[1] 弗 (futsu) was chosen for the initial fu, used by Udagawa Yōan in Seimi Kaisō (1837-1847) as 弗律阿里涅(フリュオリネ)[2] from New Latin fluorine (not used today), and by Heijirō Takehara in Kagaku Nyūmon (1867-1870) as 弗律阿𠌃母(フリュオリウム) from New Latin fluorium. Other sources say it is from English fluorine[3][4] but the Dutch translations predate English ones.

Pronunciation

Noun

フッ素(そ) • (fusso) 

  1. fluorine, F
  2. fluorine gas
  3. (dentistry, ellipsis) fluoride to prevent cavities such as sodium fluoride.

Usage notes

Commonly written with katakana instead of kanji for the 弗 portion, due to the rarity of the 弗 character.
