8.´Ê¸ÉStem
  A stem is  the existing form to which a derivational affix can be added. a stem can be a bound root ,a free morpheme, or a derived form itself.
9.ÐÎ̬ѧ¹æÔòMorphological rules
  They are rules that govern which affix can be added to what type of stem to form a new word.
10.ǰ׺Prefix
  Prefixes modify the meaning of the stem ,but usually do not change the part of speech of the original word, exceptions are the prefixes ‘be-‘ and ‘en(m)-‘
11.ºó׺Suffix
  Suffixes are added to the end of stems, they modify the meaning of the original word and in many cases change its part of speech. 3.In using the morphological rules, we must guard against Over-generalization.

4.Compound features:
¢Åorthographically, a compound can be written as one word, two separate words with or without a hyphen in between.
¢ÆSyntactically, the part of speech of a compound is determined by the last element.
