The first part of the compoundharebrained is often misspelled hair in the belief that the meaning of the word is .with a hair-sized brain. rather than .with no more sense than a hare..Thoughhairbrained has a long history, this spelling is not established usage.
复合词harebrained 的前半部分常被错拼为 hair ， 因为人们认为该词的含义更接近于.没什么头脑的.而不是.象野兔一样愚蠢的.。虽然后一种写法hairbrained 的产生已经有一段很长的历史， 但这种写法仍不是公认的用法
