formaldehyde
ホルムアルデヒド
解説 Definition
formaldehyde は「ホルムアルデヒド」という意味の化学物質名です。日本語のカタカナ語とほぼ同じ意味で、接着剤、建材、防腐処理などの文脈で出てきます。
Formaldehyde is a colorless, strong-smelling chemical compound with the formula CH₂O. It is used in manufacturing, adhesives, resins, and preservation, and it may be released into indoor air by certain building materials and products.
覚え方のコツ Memory Tip
formaldehyde は化学名として一語で覚えつつ、歴史的には formic aldehyde「蟻酸系のアルデヒド」に結び付く名称です。建材が release formaldehyde、研究室が sealed bottle に store formaldehyde のように使います。formic acid「蟻酸」との語源上のつながりを手掛かりにし、日常語の formal とは無関係と区別します。
Treat formaldehyde as a chemical name, but use its historical connection with formic aldehyde and formic acid as a memory aid. The formic element ultimately refers to ants, not to anything formal or official. Associate the word with practical combinations: building materials release formaldehyde, laboratories store it in sealed containers, and safety reports measure formaldehyde levels in indoor air. It is a colorless, strong-smelling compound used in resins, adhesives, manufacturing, and preservation. This network of formic acid, chemical handling, and indoor-air testing is more reliable than trying to interpret formal as an ordinary English adjective.
例文
The lab stored formaldehyde in a sealed bottle.
研究室はホルムアルデヒドを密閉した瓶に保管していました。
Some building materials may release formaldehyde into the air.
一部の建材は、空気中にホルムアルデヒドを放出することがあります。
The safety report measured the level of formaldehyde in the room.
安全報告書は、その部屋のホルムアルデヒド濃度を測定しました。

formaldehyde の語源・成り立ち Etymology
ラテン語のformica（アリ）に由来する語根form-と、有機基を示す接尾辞aldehydeが結合。かつて蟻の蒸留物である蟻酸を原料に合成された経緯から命名されました。同じ語源を持つ単語に蟻酸を指すformic acidがあります。
Formaldehyde was created as a chemical name from formic aldehyde, reflecting its relationship within early chemical nomenclature to formic acid. Formic comes from Latin formica, “ant,” because formic acid was historically obtained from ants. Aldehyde itself was coined from a shortened form of “alcohol dehydrogenated.” Thus, the formal- sequence here is historical chemical word formation and is unrelated to the everyday adjective formal.
