漢語(yǔ)翻譯：
ad. 然而, 無(wú)論如何, 究竟怎樣
conj. 然而, 可是詞意辨析：
but, however, still, yet, nevertheless, while, whereas這些連詞或副詞均含“但是，可是，然而，而”之意。
but: 口語(yǔ)常用詞，語(yǔ)氣較強(qiáng)，泛指與前述情況相反。
however: 表轉(zhuǎn)折關(guān)系，語(yǔ)氣稍弱于but，連接性也弱一些，因而常作插入語(yǔ)。
still: 語(yǔ)氣強(qiáng)，多用于肯定句或疑問(wèn)句。指盡管作出讓步，采取措施或表示反對(duì)，但情況仍然如故，無(wú)所改變。
yet: 常用于否定句，語(yǔ)氣比still稍強(qiáng)。指不管作出多大努力或讓步，仍達(dá)不到預(yù)期的結(jié)果。
nevertheless: 指盡管作出完全讓步，也不會(huì)發(fā)生任何影響。
while: 表對(duì)比，一般可與whereas換用，但程度弱一些。
whereas: 表對(duì)比，一般可與while互換。but, however這兩個(gè)連詞都有“但是，可是，然而”之意。
but: 連接兩個(gè)分句或有關(guān)部分，表示轉(zhuǎn)折或邏輯上的對(duì)比關(guān)系，使用最廣，口語(yǔ)中更為常見(jiàn)。

we love peace but we are not afraid of war.
我們熱愛(ài)和平，但我們并不害怕戰(zhàn)爭(zhēng)。

however: 轉(zhuǎn)折意味比but弱，連接的兩個(gè)分句或有關(guān)部分的關(guān)系較為松弛，后一部分常起附帶說(shuō)明或襯托作用。however常以插入語(yǔ)形式出現(xiàn)在句子中間，前后用逗號(hào)隔開(kāi)，也可置于句首或句末。

later，however，he decided to go.
可是后來(lái)他決定去了。
