Etymology[edit]

Compound of (futsu, used phonetically) +‎ (so, chemical element). First used by Morisaburō Ichikawa in Rika Nikki (1872).[1] (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[edit]

Noun[edit]

フッ素 (hiragana and katakana フッそ, rōmaji fusso)

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

Usage notes[edit]

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