如果有人对你说“You are a real blinkard”，那你可注意啦，对方并不是认为你眼神不好，而是在diss你的智商。
英语中有很多委婉表达“某人很蠢”的句子，比如最常见的，the light is on but nobody is home（灯亮着，家里没人）,a few cards short of a deck（一副扑克里少了几张牌），等等。
1. Anserine (adj.) [ 'ænsə,raɪn ]
Definition: stupid, silly
Anserine comes from the Latin anser, meaning "goose." The word is indeed used on occasion to mean "resembling a goose," but the 'silly as a goose' sense preceded this by a considerable length of time.
2. Cretinize (v.) [ 'kri:tənaiz ]
Definition: to reduce to a condition of extreme stupidity
The word cretinize comes, rather obviously, from the older word cretin. This older word is most commonly used today in the sense of “a stupid, vulgar, or insensitive person,” although it initially meant “one affected with cretinism” (a genetic abnormality, and using cretin in this sense is now considered quite offensive).
3. Blinkard (n.)
Definition: a stupid, slow-witted, or obtuse person
The original meaning of blinkard was “one that blinks with or as if with weak eyes,” which soon added the pejorative meaning listed above. If you are a person who blinks often please accept our apologies for the English language, which can on occasion be needlessly cruel.
4. Dunderheaded (adj.)
Definition: being a dunderhead
What is a dunder, and why do we use this word to insult people in a somewhat mild fashion? Alas, this is but one more unknowable in a long line of things that etymology has not yet figured out. It may come from the Dutch word for “thunder” (donder), but no one is sure about that. What we are sure about is that there are a great number of words for “stupid” or “stupid person” ending in -headed or head. A partial list includes the following: airhead, blockhead, bonehead, bullhead, bubblehead, buffle-headed, butthead, chucklehead, deadhead, fathead, flathead, hammerhead, heavy-headed, idleheaded, ironhead, jolt-headed, jughead, knucklehead, loggerheaded, lunkhead, meathead, muddlehead, pinhead, pinheaded, ramhead, saphead, sheepheaded, sheepshead, thickhead, and wooden-headed.
Dunder是什么意思，为什么人们要用这个词委婉地羞辱人？唉，这也是众多尚未弄清词源的单词之一。Dunder可能起源于荷兰语donder，意思是“雷声”，但还没有确切的证据。我们可以肯定的是，很多表示“愚蠢”、“蠢人”的单词都是以-headed或-head结尾的。比如下面列出的部分单词：airhead, blockhead, bonehead, bullhead, bubblehead, buffle-headed, butthead, chucklehead, deadhead, fathead, flathead, hammerhead, heavy-headed, idleheaded, ironhead, jolt-headed, jughead, knucklehead, loggerheaded, lunkhead, meathead, muddlehead, pinhead, pinheaded, ramhead, saphead, sheepheaded, sheepshead, thickhead, wooden-headed都表示“愚蠢”、“迟钝”或“呆子”的意思。
5. Addlepated (adj.) [ 'ædl,peitid ]
Definition: stupid and confused, mixed up, or eccentric
The pate portion of addlepated comes from an older word for "head," in use since Middle English, and of uncertain origin. The addle portion may be traced back to the Old English word adela, meaning “filth, filthy or foul-smelling place.” As an adjective addle first had the meaning of “foul smelling and putrid” (specifically said of an egg), and later came to mean “confused or muddled.”
6. Nescient (adj.) [ 'nesiənt ]
Definition: exhibiting or characterized by nescience: ignorant, agnostic
Nescient, science, and omniscient all share a root: each comes in part from the Latin word scire, meaning “to know.” Nescience, then, is "lack of knowledge or awareness."
Nescient, science（科学）和 omniscient（无所不知的）的词根都是拉丁语单词scire，意为“知道，了解”。Nescience则是“无知”的意思。
7. Bêtise (n.) [ be'ti:z ]
Definition: an act of foolishness or stupidity
Bêtise came to English from the French word bête, which has the meaning in that language of "idiot," or, more literally, "beast". In addition to an act of stupidity, bêtise may refer to stupidity or ignorance in general.
