gay.ness
n.（名詞）
The wordgay is now standard in its use to refer to the American homosexual community and its members;in this use it is generally lowercased.Gay is distinguished from homosexual in emphasizing the cultural and social aspects of homosexuality.Many writers reservegay for male homosexuals, but the word is also used to refer to homosexuals of both sexes;when the intended meaning is not clear in the context,the phrasegay and lesbian should be used. Like the other names of social groups that are derived from adjectives (e.g.,Black ), gay may be regarded as offensive when used as a noun to refer to particular individuals, as inThere were two gays on the panel; here a phrase such asgay people should be used instead. But there is no objection to the use of the noun in the pluralto refer to the general gay community,as inGays have united in opposition to the policy. See Usage Note at homosexual
單詞gay 其用法已被普遍接受， 指的是美國(guó)的同性戀團(tuán)體及其成員；在這種用法中，它一般小寫(xiě)。Gay 區(qū)別于 homosexual， 前者強(qiáng)調(diào)同性戀者的文化和社會(huì)方面。許多作家把gay 限定于男性同性戀者， 但這個(gè)單詞也可用于指兩種性別的同性戀者，當(dāng)上下文的言外之意不太明確時(shí)，詞組同性戀男性和同性戀女性 可以被使用。 就象其他從形容詞派生來(lái)的社會(huì)群體名詞一樣（如，黑人 ）， gay 如果當(dāng)作為一個(gè)名詞使用，指一些特殊的個(gè)體時(shí)，可能會(huì)被認(rèn)為帶有攻擊性， 如在There were two gays on the panel； 在此處應(yīng)該用詞組gay people 來(lái)代替。 但是并沒(méi)有人反對(duì)其名詞的復(fù)數(shù)形式，指一般的同性戀團(tuán)體，如句子同性戀者們已經(jīng)團(tuán)結(jié)起來(lái)對(duì)抗政策 參見(jiàn) homosexual
