英语最常用的29个前缀和25个词根

SAT/GRE/TOFEL/考研 英语单词必备词根词缀

Many studies show the importance of building children’s vocabulary. One study has shown that a set of 20 prefixes and 14 roots, and knowing how to use them, will unlock the meaning of over 100,000 words. A similar study showed that a set of 29 prefixes and 25 roots will give the

meaning to over 125,000 words. Imagine adding suffixes! Below are lists of prefixes, suffixes, and roots – with their meanings and example words. Reviewing these also can help many ELL

students to see relationships between and among languages. Many prefixes have a basis in Latin – also the basis for Spanish, French, and Italian – or Greek.
