For most comparatives of one or two syllables, use of -er seems to be fading as the oral element in our society relies on more before adjectives to express the comparative; thus prettier is more pretty, cooler is more cool [Barnhart].
對於大多數一兩個音節的比較級,使用 -er 似乎正在消失,因爲我們社會的口頭元素依賴於在形容詞前使用 more 來表達比較級; 因此, prettier 是 more pretty, cooler 是 more cool [Barnhart]。
