Suffixes Improve Vocabulary Too

      Using suffixes which are placed after a word root to change the meaning of the word or the part of speech is another easy way to increase vocabulary and reading comprehension.  The suffixes and prefixes don’t ALWAYS work.  You might end up creating a “neologism” which is a new or invented word.  Creative but not always desirable.  Below are listed a few favorite prefixes:

-able capable of being or doing fixable
ac, iac pertaining to cardiac
al, eal pertaining to medial
algia pain neuralgia
ary pertaining to binary
ate having the function of legate
ation process of aeration
cide capable of killing herbicide
