90 common roots, 30 prefixes 30 suffixes

English has a high degree of logic and consolidation of the grammar, is recognized as the world's international communication language.
many words in English are derived words (the structure can usually be summed up as: prefix + root + suffix).
commonly used stems about 400 (the daily term 90 is enough), commonly used prefixes about 30, commonly used suffixes about 30, so as long as you remember them and combine, 3000 vocabulary is mastered.
(1), Root:
The word is summed up according to the root, to learn a 10 effect. A word memory method that is respected by Western scholars and is quite traditional.
1. Root: The most fundamental part of the word, representing its most basic meaning. is a simple letter combination of the early days of English origin used to express specific things. Ex: Root Act (do, Act), derived from the Latin actus.
2. There are many changes in each language in the development process, as well as the principle of variation in the roots:
1) A root can have a lot of small changes, together to express the same meaning. Ex:acid (sour, sharp), can be mutated into ACER,ACRI.
2) completely different multiple roots express the same meaning. Ex:acid,bitter,sour,sharp, these four stems are completely different etymology, can be expressed as "sour, bitter."
3) A root has the original meaning also has the extension meaning (Initiation, association). Ex:hum, original meaning: Earth, extension of righteousness: human (in the Christian Bible, the human ancestor Adam and Eve is God with Earth).
