由形容詞形成副詞

在多數情況下,只要在形容詞字尾加 ly 即可形成副詞。

形容詞 副詞

slow slowly

如果形容詞字尾是 y,則去掉 y 再加 ly 即可。

angry angrily
happy happily
lucky luckily

如果形容詞是以 able、ible 或 le 結尾,則把 e 去掉再加 y 即可。

形容詞 副詞
probable probably
terrible terribly
gentle gently

如果形容詞是以 ic 結尾,就加上 ally。但有例外:public -> publicly

形容詞 副詞
basic basically
tragic tragically
economic economically

有些副詞和形容詞同形:early、fast、hard、high、late、near、straight 以及 wrong
