<注釋>The origin offlimsy, although uncertain, is not completely obscure.The word is first recorded in English in the 7th century in a dictionary of cant, the jargon of people such as thieves and beggars.Its early senses .frail. and .trivial.as well as its form may link it withflim-flam, recorded first around 538.The nounflim-flam could mean .a piece of nonsense or idle talk,. and the adjective could mean .frivolous.. Flim-flam itself is a reduplication in which the patternfl—m occurs twice, the first time with the sound ();the second, with the sound (2). Flim may be related to the Old Norse wordflim, meaning .a lampoon, libel..
Flimsy 的詞源雖然不確定， 但并不是完全不清楚。這個單詞在7世紀首次用英語記載于一本行話字典里，即記載如小偷和乞丐等人所使用的隱語的字典。它最初的意思是.脆弱的.和.輕微的.，其形式可能與flim-flam 有聯(lián)系， 首次記載大約是在538年。Flim-flam 作名詞時意思為.一句無意義的或無聊的話，. 作形容詞時可當作.瑣屑的，無意義的.講。 Flim-flam 本身是一個重疊詞，fl-m 這樣形式出現(xiàn)兩次， 第一次是與語音（i）組合；第二次是與語音（a）組合。 Flim 可能與古斯堪的納維亞語flim 有關， 其意思為.諷刺，誹謗.
