單詞是學習英語的基石，但是“背單詞”是很多英語學習者最頭疼的事情，英文單詞背了忘，忘了背，翻來覆去效果還不好！實際上，就像我們漢字有“偏旁部首”一樣，英語也有類似的“詞根詞綴”，掌握了英語構詞規律，英語單詞記憶就輕松多了！

depreciate

下面我來看英語單詞：depreciate [dɪ'priːʃieɪt] v. 貶值；降價；輕視

depreciate=de preciate

前綴：de-=down ,去掉；詞根：preci=price, 價值；後綴：-ate,動詞後綴，liberate. 當然，-ate , 也可以做形容詞後綴， 例如 fornate.整個depreciate 就是“去掉價值”，也就是“貶值、折舊”等意思
