フッ素

Daijirin
Daijisen
Udagawa Yōan
ja:フッ素
ja:松村明

Compound of 弗 (futsu, used phonetically) + 素 (so, “chemical element”). First used by Morisaburō Ichikawa in Rika Nikki (1872). 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) 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 but the Dutch translations predate English ones.

Battle of Dan-no-ura
Daijisen#Online_search_engines
Nagaoka, Niigata
Nihon Kokugo Daijiten
ja:平頼盛
ja:親知らず

Compound of 親 (oya, “parent”) + 知らず (shirazu, “not know”, classical negative form of the verb 知る (shiru, “to know”)).
First cited definitively to 1595, although the place name might be based on a poem from the early 1100s.
Additional information about the place name
The longer version of the place name is 親不知子不知 (Oyashirazu Koshirazu, literally “not knowing parents, not knowing children”), and might come from a poem written by the wife of the samurai 平頼盛 (Taira no Yorimori) in the late 12th century, in memory of her two-year-old son who had perished there. People in those days could only bypass the cliff by traversing a narrow strip of land at sea level, and in stormy weather, huge breakers could easily sweep people away unless they held on tightly to the rocks, an act said to make them forget about their parents and/or children. The young boy had been swept away by such a wave as he and his mother traversed the base of the cliff while they fled to 五百刈 (Gohyakkari) village (currently part of present-day Nagaoka) following the Battle of Dan-no-ura.
The alternative spelling 親不知 uses the 漢文 (kanbun) spelling 不知 for the shirazu portion.

compound

classical negative form of the verb <i class="Jpan mention" lang="ja">知る</i> (shiru, “to know”)

col-top

Short for 親不知歯 (oyashirazu-ba, literally “parents not-knowing tooth”). a wisdom tooth (from the likelihood that the wisdom teeth do not erupt until after no longer in daily contact with one's parents, due to moving or death)
