int. 喂;哈罗
n. 表示问候, 惊奇或唤起注意时的用语
n. (Hello)人名;(法)埃洛
Hello, formerly an Americanism, is now nearly as common as hullo in Britain (Say who you are; do not just say 'hello' is the warning given in our telephone directories) and the Englishman cannot be expected to give up the right to say hello if he likes it better than his native hullo. [H.W. Fowler, "A Dictionary of Modern English Usage," 1926]
