Reading New Words...

...will be easier if you look for:
             root words
             prefixes
             suffixes

What is a root word, prefix, and suffix?
A root word is a word without any word
parts added to the beginning or end.
A prefix is a word part placed before a root word.
A suffix is a word part placed after a root word.

Let's at some examples.

word	prefix	root word	suffix
rewashed	re	wash	ed
preheating	pre	heat	ing
unbaked	un	bake	ed
rewinds	re	wind	s
rerunning	re	run	ing

   Note:
      There are times when the root word must be
               changed when a suffix is added.
                  When a root word ends in a silent "e", the e is
                           dropped before adding a suffix.
                                 (ex.) un + bake + ed   becomes    unbaked

                  When a root word ends in a consonant, the consonant is
                         "doubled" before adding a suffix beginning with a vowel.
                            (ex.) re + run + ing   becomes    rerunning
