n.（名詞）
<注釋>.‘O frabjous day! Callooh! Callay!’ He chortled in his joy..Perhaps Lewis Carroll would chortle a bit himself to find that people are still using the wordchortle, which he coined in Through the Looking-Glass, published in 872. In any case,Carroll had constructed his word well, combining the wordschuckle and snort to create it. This type of word is called a blend or a portmanteau word.InThrough the Looking-Glass Humpty Dumpty uses portmanteau to describe the word slithy, saying, .It`s like a portmanteau—there are two meanings packed up into one word. (the meanings being .lithe. and .slimy.).
.‘噢，今天真是太棒了’他高興地大笑著說.。也許劉易斯·卡羅爾發(fā)現(xiàn)人們還在使用他872年出版的透過鏡子 一書中創(chuàng)造的 chortle 一詞時，他自己會大笑起來。 無論怎樣，卡羅爾把chuckle 一詞和 snort 一詞結(jié)合起來創(chuàng)造的這個詞，創(chuàng)造得很不錯。 這種形式的詞稱為混合詞或合成詞。在透過鏡子 一書中矮胖子用 portmanteau（合成詞） 一詞描述 slithy 一詞說， .它象個混成詞--有兩個意思加在一起放進(jìn)一個詞中.（意思是.柔軟的.和.粘性的.）
