覚え方のコツ Memory Tip
標準的な形 insidious「気づかれにくく進行する、陰険な」から先頭の in- を落とした、非常にまれな形として覚える。sidious plan や sidious motives のように、表面に出ない悪意や陰謀を形容する。ただし通常の英作文では insidious、underhanded、malicious を使うのが安全。
Treat sidious as a rare shortened form of insidious, with the initial in- removed. Both suggest hidden harm rather than open aggression: a sidious plan or sidious motive works secretly and may not be recognized at first. Connect it with underhanded when the focus is dishonest methods and with malicious when the focus is an intention to harm. Because sidious is not standard in most modern writing, use insidious in ordinary English unless you are reproducing a particular name, dialect, or stylistic usage.
例文

sidious の語源・成り立ち Etymology
sidious は標準英語ではまれで、ふつう insidious の短縮形と考えられます。insidious はラテン語 insidiosus「待ち伏せする、陰険な」からで、さらに in-「上に」＋ sedere「座る」にさかのぼります。じっと潜んで害をなす感覚が「陰湿な」につながります。関連語は insidious, sedentary。
Sidious is a rare form generally understood as a shortening of insidious. Insidious comes through Latin insidiosus, meaning “cunning” or “treacherous,” from insidiae, “ambush” or “plot.” That Latin family is connected with insidere, literally “to sit in or upon,” formed from in- and sedere, “to sit.” The historical image is of danger sitting concealed in ambush, which led to the modern sense of secretly harmful or deceitful.
