alcohol

★★★
🇺🇸 /ˈælkʌhˌɑl/
noun 编号: A00996 牛津3000 BNC #2654 COCA #2191
alcohol 主要指酒精,尤其是饮料中的乙醇;在化学语境中也可泛指含羟基的有机化合物。
💡 记忆钩子
把它想成“提炼出来的精华”:这个词最早和极细的粉末有关,后来引申为蒸馏得到的液体精华,最终主要指乙醇,以及含乙醇的酒类饮料。
📝 学习建议
  • 学习时先掌握“乙醇”和“酒类饮料”这两个日常核心义,再记住化学中的广义用法。
  • 不要把 alcohol 一律理解成“酒”;在医学和化学语境中,它常特指乙醇或一类化合物,而不是某种具体饮料。
📖 中文释义
noun
  • common 含羟基的有机化合物
    📖 在化学中,alcohol 是一大类含有羟基(-OH)的有机化合物的总称;乙醇只是其中的一种。
    💡 常见模式是“an alcohol”或“alcohols”后接化学名称、分类或性质。这个义项主要见于化学、医学和科学说明文,不能因为看到 alcohol 就自动理解成可饮用的酒精。
    countable
    Methanol is a highly toxic alcohol.
    甲醇是一种毒性很强的醇。
  • core 乙醇
    📖 这里特指乙醇,也就是许多酒类饮料中使人产生醉意、并可作为消毒剂或溶剂使用的那种酒精。
    💡 常见模式是“alcohol in the blood/body”或“alcohol-based + 名词”,也常和医学、毒性、消毒等话题连用。这个义项比“酒类饮料”更科学、具体;在正式说明中不要把它误当成某一瓶酒。
    colloquial countable uncountable
    The test found a small amount of alcohol in his blood.
    检测发现他的血液中含有少量乙醇。
    This hand sanitizer is alcohol-based.
    这款洗手液是以乙醇为主要成分的。
  • core 酒类饮料的总称
    📖 在日常语境中,alcohol 常泛指含乙醇的酒类饮料,如啤酒、葡萄酒和烈酒,而不是单指其中的化学成分。
    💡 常见模式是“drink alcohol”“avoid alcohol”或“alcohol and driving”,通常作不可数名词使用。它是较中性的总称;说具体种类时要改用表示啤酒、葡萄酒或烈酒的词,不要把 alcohol 当成某一种酒名。
    uncountable
    She stopped drinking alcohol last year.
    她去年戒酒了。
    Never drive after drinking alcohol.
    喝酒后绝对不要开车。
  • rare 极细的粉末
    📖 这是已经过时的旧义,指任何极细的粉末,和这个词后来表示“提炼出的精华”的历史发展有关。
    countable obsolete uncountable

🌳 词源
源自阿拉伯语中表示“锑粉、极细粉末”的词,后来经中世纪医学和炼金术文献发展出“蒸馏所得的精华”以及“乙醇”的含义。
Akkadian 𒎎𒋆𒁉𒍣𒁕 (guḫlum)bor. Aramaic כוחלא (kuḥlā)bor. Arabic كُحْل (kuḥl) Andalusian Arabic اَلْكُحُول (al-kuḥūl)bor. Medieval Latin alcoholder. Middle English alcofol English alcohol First attested in the 15th century from Middle English alcofol, from Middle French alcohol or Spanish alcohol, derived from the Medieval Latin rendering alcohol transmitted in medical or alchemical literature of Arabic اَلْكُحْل (al-kuḥl, “kohl”), which in Andalusian Arabic also bore the form كُحُول (kuḥūl), قُحُول (quḥūl); bearing thus the meaning of stibnite first, then generalized in meaning to a powder obtained by triturating a material, then also to liquids obtained by boiling down, and specialized to mean spirit of wine, ethanol, in the 18th century, then the narrow chemical sense after 1850. Doublet of alcool and kohl. Various old etymological notes. * Bartholomew Traheron in his 1543 translation of John of Vigo introduces the word as a term used by "barbarous" (Moorish) authors for "fine powder": the barbarous auctours use alcohol, or (as I fynde it sometymes wryten) alcofoll, for moost fine poudre. * William Johnson in his 1657 Lexicon Chymicum glosses the word as antimonium sive stibium. By extension, the word came to refer to any fluid obtained by distillation, including "alcohol of wine", the distilled essence of wine. * Libavius in Alchymia (1594) has vini alcohol vel vinum alcalisatum. * Johnson (1657) glosses alcohol vini as quando omnis superfluitas vini a vino separatur, ita ut accensum ardeat donec totum consumatur, nihilque fæcum aut phlegmatis in fundo remaneat. * Some authorities, including Rachel Hajar, suggest that the ultimate etymon was the Arabic term اَلْغَوْل (al-ḡawl, “bad effect, evil result of headache”) (as used in Qur’an verse 37:47, but this word is rather poetical and could for topical reasons not have been picked up from Arabic by Medieval writers, and aside from that the relation to stibium is well documented.
