The wordfulsome is often used, particularly in the expressionfulsome praise, to mean simply .abundant,. without any implication of excess or insincerity.This usage is etymologically justifiedbut may invite misunderstandings in contexts in which a deprecatory interpretation might also be available.The sentenceI offer you my most fulsome apologies may unintentionally raise an eyebrow, where the use of an adjective likefull or abundant would leave no room for doubt as to the sincerity of the speaker`s intentions.
單詞fulsome 經(jīng)常使用， 尤其在表達(dá)溢美之辭 時(shí)， 只表.豐富.而沒有.過分或虛偽.的意思。根據(jù)詞源學(xué)判斷此用法是有道理的，但卻會(huì)在一些場(chǎng)合得到貶義的解釋而引起誤會(huì)。如我對(duì)你抱歉到家了 ，這句話會(huì)無意中使對(duì)方皺起眉頭， 若是此處用full 或 abundant 之類的形容詞， 就不會(huì)使聽者對(duì)于說話者誠(chéng)摯道歉的意圖產(chǎn)生懷疑了
